Failed to Download File error when launching Minecraft

It doesn't affect only version 1.19.3, it goes from 1.18 to the latest one, im having this issue, and been trying to find some information and solutions, but until i do all i can do is play on bedrock and wait for it to have a solution that works

@KenGreen1 Thanks for the info, I'll update the report. Edit: Unfortunately affected versions only allows latest, but I updated it in the Environment.

Just a note about the downloading each file section, I have done about 20 now and more keep coming so that is not a fix for the “failed to download file” section, a couple of my screenshots are already linked in the post

After I explicitly set the path to java for the profile and curl'd the missing files, the launcher finally allowed me to run Minecraft. However the panorama and the Realms "Get a trial!" map screenshots were missing (the violet-black "missing texture" texture was displayed instead). I restarted Minecraft, the launcher downloaded additional 100MB of things and now everything looks fine in game.

When manually downloading missing files, for every file I was getting the same error as in launcher ("closed with bytes remaining") for a short while, but after a few tries the download succeeded and I could move on to the next file.

FYI, Launcher team is actively working on this bug. We think we've found the root issue and are aiming to have a testable fix on Beta early next week - Mon or Tues.

at the command prompt of the error

'downloads' is not recognized as an internal command
or external, an operable program or a batch file.

@DudyNity That means you didn’t copy paste the entire command.

(6) Could not resolve host: libraries.minecraft.net

why that?

having the same problem

@pizza999 at least u don't have to buy minecraft again (if the workaround did work (hopefully))

Please see if you're still having the issue on the latest Beta version of the launcher.

You can access the beta version by clicking 'Settings' and selecting 'Use beta version of the Launcher'

Please only add comments that contribute to the bug report also. Please don't comment saying "I'm also having this issue", instead add a vote or watch the issue for updates.

Updated to beta version of the Launcher (b.2.3.592-1.1.128) and I am still experiencing the issue.

Failed to download file.

The workaround listed above does work still, but, obviously, that's not ideal.

I tried the missing file curl tip in the guide above to manually download the missing files but the problem keeps happening where it cuts to say :

C:\Users####\Downloads> curl -O https://resources.download.minecraft.net/86/868c7a7c4d9358d631fa2f9abfc6bbf05d88292d

curl: (18) transfer closed with 9798451 bytes remaining to read

I spam tried to download the file and it gave the closed transfer mark on that same 9798451 bytes each time.

On another note, after getting the file errors and trying to launch the instance again I get a

@iedyl that's why theres a Java install process in the issue, try doing that workaround process, if it doesn't work, try reinstalling everything, and do the process all over again

Bug still present is lastest beta version of laucher.

I can confirm that problem is partially resolved - imo Java runtime downloads correctly. Game opens without some textures, after closing error & clicking play again (see following attachment for an example)

Following error still shows:

I've performed a few attempts made of deleting .minecraft & opening launcher and downloading game. Every time the same happens.

Launcher version: v.2.3.585-1.1.28 (for Windows 10/11)
OS version: Windows 10 Home 22H2

@kuzynprocesor1 the fix for your issue with the missing files, is described within this report underneath the "missing files" header.

Fixed my issue by launching the MC launcher as administrator. (windows 8-11)

Following up from my earlier comment, I can now open Minecraft with no issues if I run the latest beta of the Minecraft Launcher as an administrator, as stated by 2007IGN.

I can't install, I've tried all the tips from the staff. 😞

what do you do if you are trying to install a missing file that gives a URL that's not "resources.download.minecraft.net/xx"? And what if the path it wants to download to doesn't exist?

@Museical3739 If the folder doesn't exist, create it in .minecraft\assets\objects. What's the URL?

Okay, so I tried going through the whole manual installation thing and got stuck on a specific file, receiving this message.

After downloading the file and putting it into the proper folder, it is deleted or moved when the launcher tries to access it, leading to the launcher stopping and the game not working properly. If anyone had this same problem and found a workaround, please let me know.

Solved it, if anyone else has this issue you need to go find the file somewhere not from Microsoft, download it, then put it into AppData\Roaming\.minecraft\assets\objects\b8\ and rename it as "b83bbafa9799680da24f10215de2c40b73ce1fe3", after that it should work and you can continue manually installing the other missing files.

I did some experimenting with this my self I tried older versions of Minecraft it only affects 1.13.1 through 1.19 and above
I just uninstalled the game awhile back and wanted to play again so I reinstalled it but ever since I reinstalled it I get this error. this is dumb we should not have to jump through hoops to play a stupid video game. it resolved it self after I ran as administrator but still this is problem needs fixed

@Log

This issue does affect versions further back than 1.13, but it may not for you.

I agree that its different for everyone.

If you are unable to pull down the files manually, please ask for assistance at Community Support.

I want to share my experience fighting and overcoming this bug.

when i would click the play button, the green bar at the bottom would show that it was downloading, and would then stop and throw a error that it had failed to download ancestry.ogg . if i would try to play minecraft again, then the error message would switch to not being able to find java.

first, i removed the runtime folder from the /program files (x86)/minecraft launcher folder and put it somewhere safe. i tried again and the same pattern of errors would occur.

next, i pasted the url from the error message into my browser and downloaded the file. i then pasted it into the folder described in the error message.

upon trying again, a new error message appeared, this time for a different song, left_to_bloom.ogg . i repeated the process of downloading the file.

i moved the runtime folder back where it belongs and tried it again, and this time, the downloading process went smoothly and minecraft opened, much to my relief and delight. i don't think the order of these things was important, and moving the runtime folder likely didn't do anything. however, i included that information for the sake of completeness in case it actually did something.

I just want to add on to this bug report with another fix that's associated with this bug report.

If the missing file type is a .jar file, please follow these instructions to change your DNS: 1.1.1.1 DNS change instructions

The launcher should download the .jar files with this fix. You will still have to download the other missing files afterwards, using the instructions in the bug report.

Even after running the command I got the error attached, does anyone know how to fix it?

I've not been able to play MC since 1.19.3 came out. When through all the "fixes" I knew like reinstalling Minecraft. Downloading the missing files manually, until it got to authlib-3.18.38 which I can't find a copy anywhere. My sister and I both have fairly new gaming computers. 1.19.3 still worked on hers, but she would get an error message. Sound would not work, but she could still play.

I kept hoping that the next update would fix the error. Now 1.19.4 is out and both our computers are missing https://libraries.minecraft.net/com/mojang/authlib/3.18.38/authlib-3.18.38.jar

I've tried following directions above but still nothing works. I only get error messages when I try to download the file manually.  After several months of no longer being able to play on our Realms server I share with friends, I'm reached my limit of frustration.  The update didn't fix the issue but made it worst for my sister. If we can't find a solution soon, I'm going to have to turn off our Realms server until this issue is finally resolved. 

I'm open to suggestions of how to fix this issue. My sister and I have tried many things, but so far nothing has worked. 

I am still not yet solved this problem.

I have try to download the file manually, however, once I re-start by click into the Java edition, it will pump up the error message with the same file name that I copied already.

Just looped as a dead end.

Could anyone know how to fix it?

I also seem to have this issue. And a fix that has worked for me is literally just connecting to a VPN. works with absoloutly no issues apart from slower download speed because of the VPN.

Without the VPN connected its as if the launcher fails to connect to the internet.

I've been experiencing this issue, but with the updater, since a launcher update that must have happened just hours ago. The launcher would not update repeatedly (and crashed itself) until I tried it with a VPN. The native updater log contains many entries like this:

This also is happening to me. I am doing the steps but every time I do it and relaunch MC another not found error pops up.

We think we've narrowed in on the cause of this, and hopefully it's been mitigated; please try again and tell me if the issue persists! Hopefully it's not happening anymore.

My friend just bought the game and is having the same issue they downloaded the launcher from minecraft.net if thats means anything and the issue has happened twice in the last 2 hours with a full reinstall in between attempts. The error is attached in a screenshot

I have been having this issue as well, tried some workarounds listed and still no dice.

Not sure if same issue, but when trying to download 1.7.10 (for a modpack), it failed on both MultiMC and vanilla launcher, I tried https://libraries.minecraft.net/com/mojang/netty/1.8.8/netty-1.8.8.jar in browser and also "curl https://libraries.minecraft.net/com/mojang/netty/1.8.8/netty-1.8.8.jar" and that also failed until I either turned on VPN or changed DNS to 1.1.1.1 or 8.8.8.8, so I guess its a dns issue (for reference my DNS IP seems to be owned by my ISP, but I don't wanna publicly share which it is)

@lathamm and @FiNiTe_weeb , change your computer's DNS settings following these instructions.

After doing this, navigate to AppData\Roaming\.minecraft , and delete (or rename, if you're worried) the libraries folder. Doing this should trigger the launcher to download the library files again.

In an unrelated comment, anyone getting the missing java.dll errors as of last week, it is unknown if any of the provided solutions in this bug report will fix it.

I installed Minecraft a couple nights ago, and I am also getting this error. I am attaching an image of both the error on the first launch attempt and the error after the second launch attempt.

First launch:

Second launch:

So been getting same issues mentioned with : 

First launch:

Second launch:

So I have tried to workarounds mentioned above When attempting to Download the missing files with the cmd.....

Also downloading the files manually following the link does not work, download will stop with a network error..

then for the second issue with java I have followed the steps mentioned above to find the jawa.exe file. I don´t get the error prompt anymore but now instead the game crashes.. ive had different crash errors : 

1. Unable to launch java.lang.reflect.InvocationTargetException at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:77) at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.base/java.lang.reflect.Method.invoke(Method.java:568) at net.minecraft.launchwrapper.Launch.launch(Launch.java:159) at net.minecraft.launchwrapper.Launch.main(Launch.java:30) Caused by: java.lang.NoClassDefFoundError: Could not initialize class com.mojang.blaze3d.systems.RenderSystem at ac.a(SourceFile:65) at dyr.a(SourceFile:2394) at dyr.a(SourceFile:2389) at net.minecraft.client.main.Main.main(SourceFile:206) ... 6 more
    

This issue though only happens when I try to play 1.18- 1.18.2 if I go for the latest version 1.19.4 I still get issue with Failed to Download file but no crashes. 

However I need to get 1.18.2 working :/ it is very very very frustrating, tried all kinds of work around I found online, nothing working

Update:  

I spent two hours manually transferring missing individual files from a computer where Minecraft works to my computer. After I added each file, I ran Minecraft, it would give me a different error message for yet a different missing file.  TWO HOURS of doing this, I finally got all missing files in place and Minecraft 1.19.4 actually worked. I could play normal Minecraft for the first time in three months.

Fast forward a week or so. I try to play Minecraft and its complains about more missing files.   Refuses to launch again. 

I deleted my virus protection. I tried renaming the .minecraft folder. That just led it to fussing about yet another different missing file.   I'm EXTREMELY frustrated.  I'm been a long time Java player for 12 plus years since Beta 1.3.  I've never had this problem on any computer before 1.19.3 came out. I've played on older, slow computers. I've played on gaming computers (like the one I now own). I'm a tech teacher and have Minecraft downloaded on twenty-five old Windows 7 computers in my lab. They work just fine. My students can play Minecraft, but I can't at home. (I even have lessons in my class that use Minecraft.)

Since 1.19.3, I've not been able to play the current version of Minecraft (except that brief moment after 2 hours of labor). Had to close the Realm server I shared with friends and family. 

But hey, I can still play Feed The Beast. Guess I may only be able to play older moded versions of Minecraft for now on. Destroys the hype of snapshots and new versions. I really, really, really hope they fix whatever is causing this issue.  

im in pain this stupid thing is going to make me have a heart attack, ive bascically done everything but a fresh install of windows and what do you know NOTHIN'

Same problem. NOTHING is working. This is ridiculous. Are they doing this so that we have to buy another version? (( sorry new here, my kids play.. we are trying to get minecraft on another computer and get error after error after error. Looks like this has been happening for months and still not fixed??

@Risici this has nothing to do with them wanting more money, it's a bug. Buying a new version will change nothing.

Something that seems to fix the issue sometimes is changing your DNS to something like Google or Cloudflare. Instructions here: https://1.1.1.1/dns/#setup-instructions

We are actively working on this - and yes this is a bug we've been working very actively to fix. At this point, most users should no longer be impacted by it - but if you are:

• Close your Launcher

• Open your .minecraft folder (from this location on your computer: %appdata%\.minecraft )

• Delete the "treatment_tags.json" file

• Re-Open your Launcher

That might fix it.

If it doesn't: Then try to uninstall & reinstall your launcher. There's a very good chance that will address the issue for anyone who is still facing this issue. 

Hello!

I've had the same issues as everyone else, when I open it originally it says the oshi core file is missing, and when I open it a second time it says javaw.exe isn't working. I tried the work around in this thread and it didn't seem to work.

No solutions I've tried have worked. 😞 Not uninstalling and reinstalling, not deleting my vpn, even resetting my whole computer! I've tried pretty much every solution online and nothing works, do I just have to wait until Mojang fixes this?

Something i noticed about this issue is that it is caused by network/ip, I had this problem consistently with my launcher, the missing files were exactly the same as the example you posted, but after enabling a VPN and connecting to Netherlands the issue got resolved immediately. (I used ProtonVPN and connected to a fast Netherlands server, I also did a complete reinstall of the launcher and any Minecraft instances with the VPN enabled).

Another case:

• Friend had trouble downloading this specific file: https://resources.download.minecraft.net/86/868c7a7c4d9358d631fa2f9abfc6bbf05d88292d (I suppose it's ancestry.ogg)

• We're both in Poland

• We both tried using curl to download it and both got the same result consistently (I tried it about 4 times):

  [media]

• curl: (18) transfer closed with 1409843 bytes remaining to read

• I then used a VPN to connect from US New York

• Then the file downloaded without a problem, immediately

It looks to me like it could be a CDN issue, whichever CDN it connects to from Poland has that file messed up on its servers somehow.

Edit: As of now (9 hours later), which is after Szliben's comment above, the download now works fine for me as well without using VPN.

My minecraft was working fine until day ago. Then ancestry.ogg bug started to appear, so same issue that some people from other comments have. My location is Poland, if that matters. I've tried istalling game on PC, that never had MC installed before, same error happened. However few hours ago problem resolved itself, without me doing anything, game can be installed as before. Not specialist, but I see reason to view this issue as connected to network or location
Edit: Problem is back
Edit nr 2: After like ten attempts missing file managed to dowload itself

I am seeing this issue as well. I have tried reinstalling the auncher, as well as many of the other fixes recommended, but regardless of how I do it it always says it's unable to either: locate one of the files (the same files many of these other complaints listed,) or the latter utterly bizarre error: 

From what I can tell the installer is failing to download anything at all (no new files are fetched, when trying to create a new profile (For example, to join my friend's 1.19.3 server), it can't seem to fetch anything at all. When I DID use the files that I already had downloaded that were functional not a few weeks ago, it finds something new I haven't downloaded or that has been removed (eg the a0d43b09bbd3a65039e074cf4699175b0c4724b8.png image). This problem persists with a clean installation (actually worse with that, given none of the pre-existing files I DID have were present any longer, though in neither case was minecraft ever able to launch)

I'm running Windows 11 here. Will try soon on windows 10 to see if that improves matters.

Edit: Ok, now I can't reproduce this. I'm leaving this up for posterity, but I /seem/ to have gotten the launcher to behave after (once more) pointing it to the java version I'd downloaded to try to work around the issue. I'd been trying to push the launcher to update itself, so it's possible I'd finally gotten that to succeed, and the issues were on a prior version? Not really sure what happened here, but glad it's working again.

Hey everyone, I've been having this same issue but today I managed to fix it. I did a bunch of nonsense but what I believe got it sorted was just running my Java installer again and telling it to install. Maybe my Java installation was broken somehow? Regardless, the game seems to be running fine now, I hope this helps anyone else.

Ive done all recommended things and beyond, and yet nothing. This bug is a really big problem, as it doesnt just hinder the game or cause some annoyances, it prevents us from playing the game we paid money for, please fix soon as possible.

I dont understand how this has been going on since feb.

Update Three:

After six months of dealing with this issue I can finally play!!!!!

The issue suddenly fixed itself after six months of trying to do countless suggestions. Nothing had worked. Even got my internet company to provide new router and connection. Still nothing.  Then a couple of days before the big 1.20 release, my sister tried to log in yet again, and suddenly Minecraft downloaded properly. Worked on my computer also. We could finally reopen our Realms server that we had to close months ago.

Seems to me the problem is not linked to our computers, but somehow through the internet connection. Perhaps an issue with the provider?  I'm just happy someone fixed the issue for my household. I just fear it could strike again without warning. 

A fix I found for this is to go the control panel, then go to network and internet. then go to network sharing center, then go to change adapter settings, then right click on the one your connected to and go to properties, then I unchecked the box that says IPv6 and it worked great.

@unknown and anyone else still running into this issue: Please reach out to support asap so we can gather more information from you to get your issue addressed:

https://aka.ms/MCLauncherSupport

After searching and searching, I've finally fixed this "Unable to locate Java Runtime" error.   

I'm on a 64 bit system.

Simply going to the Java download page and downloading Java 8 will install the 32 bit version of Java. 

I had to manually find and install the 64 bit version of java.  Once installed, the "Unable to Locate Java Runtime" error went away and the game loaded normally.

NOWHERE in all the support articles, forums, and what not did ANYONE mention 64/32 bit installations of Java, nor that the default "Java" install linked to in several support pages is 32 bit by default.  

I really hope this helps some of you as this was super frustrating to sort through and figure out.

Couldnt download this file because cant connect to the server from mojang

I keep hearing poland in the comments but it works after a few hours That is one of the regions having the most issues

I ran into this issue today; ran through every solution I could think of like Windows updates, sfc/dism checks, changing DNS, deleting .minecraft, etc. I was able to get around it by using my hotspot and resolved my issues with every launcher (vanilla, Modrinth, Curseforge) - funnily enough MultiMC worked with no issues. Internet and cellular through AT&T.

Wanted to follow up since I believe "I" found the issue. According to this Reddit post, Killer Control Center (KCC) was at fault. I've reinstalled Windows 10 and 11 and validated that it is installed by default which is why a fresh Windows install and only Minecraft fails. To fix this, you can disable the engine entirely by going to "Prioritization Engine" and toggling "Killer Prioritization Engine" off. I've tested the vanilla launcher and Modrinth and I'm no longer seeing any issues like before.

I'm surprised how much I had to dig to find this post, but hopefully for those of you who run into this issue can find either this comment or the Reddit post and resolve your issue.

i cant connect to https://libraries.minecraft.net/ 403 im from Kazakhstan, all this steps didnt work.
