I was having a similar issue on my server too, removing ViaVersion fixed the issue for me, reading the error logs revealed there is a duplicate handler created from some plugin called 'via-encoder'
Here's my error logs incase any dev's see this: https://pastebin.com/G5v3feNX

Aduhkiss, in your case, using Paper instead of Spigot would fix the issue.

NFRKZZ, do you have any logs when this happens?

@ver151set I'd recommend to check the logs of the backend server (behind the proxy) for errors.
If you need further help, please join our discord server & ask in #support :)

[onebeastchris]

Closing due to no further response. If the issue is still occurring with the latest version, please provide a new geyser dump & a full log.
As for the issues in the comments - those are likely issues stemming from other plugins. To verify, see the backend server log for the full error that kicked the player.
