Try to disable your virus program and your firewall and it should work. It must stay disabled everytime you want to launch the game. I guess that Mojang will make changes to make it safer for Windows 8 users.

Hardster 2013-04-19T05:09:55Z

i have the same problem.

If someone figures out what to do to 'make it work magically' – sure maybe. If not I doubt we'll be able to do much about it.

TypicalHog 2013-04-24T07:13:22Z

Is this bug on new launcher or my internet or java error ?
How can I fix it ?

You need to give more information, if you are not running on linux you have a broken java install. If you are running on linux you should add "-Djavax.net.debug=ssl,keymanager" to the arguments when you start the launcher and install the missing packages that provide the ssl core keycerts.

I have windows 7 Home Premium and java 7u21.
I tried the Java 6 but the same problem.
I modified the internet and java settings but still the same problem.
Java is OK. I have reinstall it 4 - 5 times.
Minecraft 1.5.1 works well in Java I have.

Sorry for my bad grammar.

Erik Broes 2013-04-26T10:36:11Z

Can you download the MinecraftDev.jar and run it using in: 'cmd' using:

java -Djavax.net.debug=ssl,keymanager -jar MinecraftDev.jar

You might need to specify the full path to your java for it to do.

It should give some more output.

TypicalHog 2013-04-26T18:15:11Z

I did it !
And I got this message :
Error : unable to access jarfile MinecraftDev.jar

EDIT: Deleted the attachment, showed that there is some SSL man in the middle issuing the certificate.

Erik Broes 2013-04-26T18:49:31Z

Riiiight so i can close this ticket?

TypicalHog 2013-04-26T19:05:42Z

What I can do ?

TypicalHog 2013-04-26T19:09:52Z

This is error ! Attachment is up in pictures !

Erik Broes 2013-04-26T21:01:09Z

You should put the MinecraftDev.jar in the same folder as where you execute that command.

In your case that would be: C:\Users\Korisnik

TypicalHog 2013-04-28T11:26:57Z

Thanks !
But it doesnot works !

TypicalHog 2013-04-28T11:35:39Z

How to change that MinecraftDev.jar always start in java insted of comand prompt ?
My mistake ! Sorry ! In picture. I cant change it !

Erik Broes 2013-05-02T18:34:31Z

Shift-right-click it and you get the 'Open With' menu again.

Erdan 2013-05-16T21:59:53Z

I'm also having many issues with the proxy - I get the launcher to synch but it is unable to display the available version (worked for a bit). The normal launcher doesn't seem to have any problem using the proxy. I had to ask my IT guy to check into it and he had to unlock quite a few port and ip, but those will most likely change all the time...

I had another round of issues with a official multi server (hosted on the amazon site) to be unlocked... I guess the handshake is initiated at some point from the server to the client? I was wondering if there was a good application to force the proxy/ a tunnel application that could bypass those issues and that you would recommend.

Or perhaps adding a command line that would connect to a server directly...

*When looking at other similar jira I stumble on this: Therefor the only logical conclusion is that your proxy fails providing SOCKS5 to https endpoints., i'ill check if our proxy support this in the course of next week...

Erik Broes 2013-05-18T22:06:12Z

We're not doing anything special. You can define usage of a SOCKS5 proxy to the launcher with

--proxyHost, --proxyPort, --proxyUser and --proxyPass

Doing so will route everything except the multiplayer connections over the SOCKS5 proxy.

Also this only fully works for 1.6 snapshots or later.

Erik Broes 2013-05-21T19:04:20Z

Is ticket still an issue? Please let us know.

Erdan 2013-05-22T14:17:02Z

For my part I can confirm that the issue is our proxy does NOT support SOCS5 connections,

Thanks!

Erik Broes 2013-06-07T21:20:16Z

Seems nothing about this problem is a problem anymore!

Baltassar Monkey 2013-07-03T16:14:20Z

I got this problem too, It is really frustrating and all the solutions to this problem are completely useless to me.
I am running windows 8, java 7u25 64 bit
I have re installed, updated, uninstalled and installed java so i cannot see the problem there.
Also the previous launcher did work perfectly and the firewall that i use allows minecraft through(and the new one too).
All the stuff about proxy server stuff i do not understand and would not like to mess around with until i am absolutely certain that it will work.
If you know the solution, have just fixed this problem or can suggest something else to help then please help. Minecraft is one of my favorite games and I can't wait to ride horses 😃 so please help!

Paul Gear 2013-07-04T10:14:12Z

This is still affecting me with the current version of the launcher. (I'm not sure how to find out the version since the main URL https://s3.amazonaws.com/Minecraft.Download/launcher/Minecraft.exe doesn't contain any version number.)

On my network i'm reasonably confident it's because we block outbound network access by default (as all responsible network admins do), and only have an HTTP proxy. (Other tickets seem to indicate that Minecraft only supports SOCKS5?) Am i understanding the situation correctly? This is really not a good situation as HTTP proxies are the main type in common use.

Bas Uytersprot 2013-07-16T16:14:55Z

I Update it to 6.1 and its still has that screen please send me a mail of a comment an help me pleeeeeeeeeeeeeeeaaaaaaaaaaaaaaaaaaaaassssssssssssssssssssseeeeeeeeeeeee!!!!!!!

Mikołaj 2013-07-25T20:00:17Z

What should I do?

TypicalHog 2013-10-09T08:57:22Z

I know how to fix it ! 100 % ! (If you have ESET antivirus)
Go to the antivirus and click options, then Advanced settings (something like that) I dont know what actually writes because my computer is not in English version! Then go to HTTP, HTTPS and choose Don't check HTTPS protocol and click apply !
Sorry for bad english ! (If you have Google Chrome and it can't open some pages you are lucky - this will fix that too)
This worked for me 100 % if you have question tell me !

Pawelgo 2014-03-19T18:09:02Z

Write like there is in the Polish version!
I have ESET SM 7 Polish

TypicalHog 2014-03-19T18:38:16Z

Sorry, I don't use Eset anymore...

Logan Vessell 2014-09-29T21:46:41Z

I kind of have the same problem and have a temp solution but it's just my comp. BUT You might not have launcher.pack.lzma in your .minecraft folder. So heres how to find it on 2 different computers:
Windows: Go to "Start' or "Run" and type in %appdata%, and it will take you to "Roaming". Once there, open .minecraft.
Mac (My System!): ~/Library/Application Support/minecraft/
Once in that folder, Try and find launcher.pack.lzma. If it's not there, Then that's the prob. Just go to the link it's trying to download to which is, https://s3.amazonaws.com/Minecraft.Download/launcher/launcher.pack.lzma and download it. Restart MinecraftLauncher or minecraft.exe, and you should be playing minecraft!
