Possible Errors from Server Log (These are from two separate disconnects):

[02:16:08] [Server thread/INFO] [minecraft/ServerGamePacketListenerImpl]: chaoticid10t lost connection: Internal Exception: io.netty.handler.codec.DecoderException: java.util.zip.DataFormatException: invalid distance too far back

[02:17:12] [Server thread/INFO] [minecraft/ServerGamePacketListenerImpl]: chaoticid10t lost connection: Internal Exception: io.netty.handler.codec.DecoderException: java.util.zip.DataFormatException: incorrect data check

Need help with this on my forge server, my friend keeps getting disconnected from the server after playing on it for 1 - 2 hours and I can't figure out why. We are both running the exact same modpack, and what is weird is that it doesn't happen to me. Minecraft version is 1.20.1, forge version is 47.4.6. I am using DatHost to host the server.

My client log: https://mclo.gs/RVSsITD

Client Modlist: https://gnomebot.dev/paste/mclogs/EJJ3HaV

Server Modlist (Note: Crash Assistant is not in the server mods, I used it get a link of the modlist using prism): https://gnomebot.dev/paste/mclogs/J6RBgoa

If any more information or files are needed than I can provide it!

Looks like it refers to something called "Burningwave - Resource releaser" - I have no idea what this is - maybe it is part of a mod

Does that happen before they get disconnected? Is that in the client log I sent? I don't recognize it either.

Maybe it refers to Entity Texture Features

Could it be a setting in its config then? I can't remove ETF as a lot of the mods and resource packs we use depend on it.

Hmm I have no idea

Is there anything else I could provide that would help to find the issue?

Maybe it refers to something outside of Minecraft - like Java or Firewall

That could be it, it would explain why it only happens to them and not me. But when sending someone an exported prism mod pack, does it not use the Java that original user uses?

No - but you can test it anyway
