When attempting to join a local server I get disconnected with a few different errors each time.
This specific server is modded, however the same problem persists in vanilla, so the mods are the issue. I've tried it with and without.
Mainly:
"Internal Exception: io.netty.handler.codec.DecoderException: java.util.zip.DataFormatException: invalid distance too far back"
"Internal Exception: io.netty.handler.codec.DecoderException: java.util.zip.DataFormatException: incorrect header check"
This happens when attempting to join from a local PC to my local server. It happens both when trying to join a singleplayer world over LAN, and when joining a local server. I've seen this has been an issue for a while with no resolutions anywhere. People are even still actively talking about this being an issue, so really it needs something to be done about it.
I believe it's an issue with compressing/decompressing packets. Whether it is happening server side, or client side, I would assume the client is the issue.
Thank you for your report!
However, this issue is Invalid.
Your game, launcher or server is modified.
If you can reproduce the issue in a vanilla environment, please recreate the issue.
Any non-standard client/server/launcher build needs to be taken up with the appropriate team, not Mojang.
Any plugin issues need to be addressed to the creator of the plugin or resource pack.
If you have problems on large servers like Hypixel, please contact them first as they run modified server software.
