Question Chat message validation failure

[TheAlastor]

Hello! I'm slowly getting desperate.
When I write an MSG on my server via the Party and Friends plugin (BungeeCord).
(It's not due to PAF, I have the same problem with e.g. Staff Chat) and
then I write to the "local" server chat again,
I get kicked from the sever. I have the following message in the console:

[WARN]: Failed to validate message acknowledgements from user
[INFO]: user lost connection: Chat message validation failure

I reinstalled the operating system, reinstalled spigot and bungeecord. No other plugins are installed. I'm using Spigot 1.20.4. (Also tried Paper) And the latest BungeeCord version. These run on Ubuntu 22.04 and Java 17. If there are questions, ask. Hope someone can help me, thanks.

This is an issue with bungeecord, or proxies in general, and how they handle commands/chat. I have a patch or two in Waterfall (but, that is EOL) that improves the situation for commands, Velocity has the Signed Velocity plugin which also further improves the situation a whole lot more until we get a more native solution. But, until that arrives, handling this stuff on the proxy is generally not advisable, the only solution would be to strip command/chat signing from the backend server, but, most of the plugins which do that generally create their own set of issues, so I can't recommend any on that front.
