Random kick when using +1.17 bungeecord

[Gunac]

Hi. I've updated bungeecord to the latest 1.17.1 version and players running minecraft +1.17 get randomly kicked with this error: java.lang.NullPointerException @ io.netty.handler.codec.MessageToByteEncoder:125
This does not happeng when running 1.16.5 or below.

There's nothing more, no log, nothing. I cannot tell why this is happening.
Does anyone know something about this? Thanks.

There's nothing more, no log, nothing. I cannot tell why this is happening.

There's no further stacktrace information in console? Not even in latest.log?

In that case, I'm not completely sure what the cause could be, however there are a few things you can do to try and solve the issue:

• Make sure you are running the latest version of BungeeCord
• Make sure your servers are allocated enough RAM
• Make sure the port/ip for each server on your network are different

If you've ensured all of these criteria, then I'm afraid I'm not sure what could be causing this issue without further information - what happens before you get kicked? Does the client try to register a corrupted chunk? Not sure.

Good luck trying to solve this, but these are just a few things I would try. I'm by no means a Bungee expert though!

Thanks for your message. I did forget to mention that I'm using FlameCord, a Bungeecord fork. I was able to find the full stacktrace of the error by enabling some debugging options. This is what I found: https://hastebin.com/omoqefufow.properties

I did contact Flamecord's developer and he said he has no idea and that it's probably a waterfall issue or an internt minecraft issue.

Yeah that stacktrace is not particularly helpful, the life of developers

This was an issue opened on the GitHub repository here, and was apparently fixed in commit 2593, in 2019

In this issue opened on a Bungee fork, Waterfall, apparently the explanation for this exception is "something on your proxy tried to send a mangled set of properties in the player list packet"

One fix for a user was to remove BungeeTabList - if you have it, try attempting the same.

If you're still not having any luck, try removing the plugins one at a time to debug if it's a plugin causing this bungee issue on the server, and if so, which one.

It's only happening to users on 1.17 or 1.17.1[DOUBLEPOST=1631474911][/DOUBLEPOST]

Unfortunately I do not have installed BungeeTablist[DOUBLEPOST=1631475113]

Happened to me a while back when I had my server and it was in 1.12.2

Any idea on how to fix it? My community can't access the server with versions above 1.17 :/
