[REALMS-1656] Keep getting kicked from servers and realms

For the past several weeks now, I am getting kicked after maybe 3 minutes from servers that I regularly play on. I joined a realm with friends a couple days ago and I've already lost track of how many times I've been kicked in 10 seconds. Is there a way to fix this? I've tried to restart my internet and make a new minecraft profile and it still happens.

The errors I get:
-Internal Exception: io.netty.handler.codec.DecoderException: java.util.zip.DataFormatException: incorrect header check
-Internal Exception: io.netty.handler.codec.CorruptedFrameException: length wider than 21-bit
-Internal Exception: io.netty.handler.codec.DecoderException: The received encoded string buffer is longer than the maximum allowed (131864411>64)
-Badly compressed packet - size of *** is below server threshold of 256
-Badly compressed packet - size of *** is larger than protocol maximum of 2097152
-OpenGL Error: 1281 (Invalid Value) | [This is upon connecting to a server/realm]

I added a report from the realm. I did a fresh install of minecraft, so I cant find the server ip to create the report.

I'm still getting this error, tens of times a day. I've even went so far as to do a clean install of my computer and reinstall Java and Minecraft. I don't see any particular errors or disconnect messages when I look through my logs or crash reports. I don't have any connection issues with other games, but all of my problems seem to be connection related (badly compressed packet) or computing (invalid header, corrupt frame length, out of bounds exceptions, varInt too big). A friend suggested that it could be firewall related, but the errors still persist after turning my firewall off

PC-1.14.6? We're only at 1.14.1 with 1.14.2 not too far away. Neveryoumind. Realized you meant the Realms 'version'

[Mod] LateLag 2020-10-17T23:26:55Z

Is this still an issue in the current version?

Just had to comment on this because I'm having the exact same issue with 1.16.4 currently.

migrated 2021-01-17T22:16:46Z

Same issue over here as well.

migrated 2021-01-21T00:11:17Z

Keep getting this too. Playing 1.16.4 and it's totally ruined the game, can't play with friends at all anymore without getting disconnected within 20 seconds

migrated 2021-02-10T06:34:00Z

Same, please give us a solution. Makes minecraft unplayable.

migrated 2021-03-10T15:13:42Z

same also still have this problem

migrated 2021-06-30T07:53:07Z

Still having the same issue... has there been any way of fixing it since this post was made ?

migrated 2021-07-06T02:38:20Z

Yeah... I'm also having this exact issue

migrated 2021-07-06T22:53:03Z

i have this exact same issue in 1.17

migrated 2021-07-06T22:59:29Z

it is the most annoying thing, makes it infuriating to play

migrated 2021-07-06T23:01:44Z

it ONLY affects minecraft and none of my other games

migrated 2021-12-03T17:15:50Z

One of the players on a realm of mine has this issue in 1.18.
We've tried reinstalling network drivers, disabling firewall, disabling antivirus.

migrated 2022-01-01T10:15:29Z

I have experienced similar situations,But then I found the problem,Below is the solution I found:

Make sure the signal connection between the computer and the router is smooth
Too many devices using the same router
A device is downloading
Place the router in a suitable location
(Rain may also affect internet speed)
Delay issues
Turn on accelerator
Options
Video Settings>>Render Distance (Reduced to "16" or below)
Video Settings>>Other>>Autosave (Amended to "24 min")
Video Settings>>Other>>Show GL Errors (Modify to "OFF")
(No guarantee of 100% success)

Any update on how to resolve this issue?

migrated 2022-08-30T00:28:57Z

Having this exact issue, I've seen it's been a thing for 7 years and there are no solutions?

Please tell me someone has some solution for this.

migrated 2022-08-30T02:04:06Z

On servers, the mod RandomPatches can resolve the issue: size of *** is larger than protocol maximum of 2097152

migrated 2022-09-18T11:33:36Z

Still, no new updates.......

Im only getting this on Hypixel and other servers, apart from cyborgmc.... also, I keep getting the google connected to that error.

It worked before I switched HDDs. Could that be the problem?

migrated 2023-09-09T18:06:53Z

This still seems to be an ongiong issue even in mid 2023.

The more common complaint I've seen regarding the error looks like it's internet/connection related, but in cases where Minecraft is the only game that seems to hiccup and disconnect while other games work just fine on the same PC? This error may need to be revisited.

We're having the same issue in our household with one of our PC's. All 3 PC's are identical except for graphics cards (1650 super, 1660 super and a 2060 super). Only one PC is affected and keeps having the "Internal Exception: io.netty.handler.codec.CorruptedFrameException: length wider than 21-bit" error comes up after about 30 second of gameplay on another computers LAN game. Swapping cards makes no difference.

The affected PC can host a LAN game and the other two can join without issues, but the affected PC cannot join games on any other PC or servers.

migrated 2023-09-27T01:58:21Z

Ok, so it appears we may have resolved the problem in our situation.

Having three identical PC's really helped. I realized that graphics cards were not the only difference in these PC's.... they all have different external wifi adapters.

The PC that was having the issues has a Panda wireless PAUD5 adapter. I swapped it to a AC1200 wifi adapter from another PC and it was then able to join LAN games and servers without any problems!

Looks like problem solved.

I'm still not sure why this problem started as the PC was using the same wifi adapter for 4 years without a problem.

Is this still an issue in 1.21?

migrated 2024-10-05T17:13:30Z

It definitely still pops up in 1.21. I got the same error around a week ago, and I can't figure out how to fix it.
