What makes you think that this is a protocol lib issue?
Anyways, you should enable the debug log level so we can see the full error

I removed the plugin because no one can join, also as you wrote in the error it says your package.

hello?

Anyways, you should enable the debug log level so we can see the full error

we can't help you without the log. you need to readd the plugin, enable the debug logging with this log4j config:
https://hasteb.in/acitefik.xml
(enable it using this command line parameter, put it before -jar paper.jar or whatever
-Dlog4j.configurationFile=/path/to/log4jconfig.xml)

then provide us the full log so we can take a look an potentially solve the issue if there is smth to solve for protocollib.

I cant play on the server with the plugin, thats why its removed. So i cant enable it

enabled now pls fix quicly cuz no one can join

...it's not magic, you have to give us the debug log. also, the problem's likely on your end.

i got the same issue on 1.8.8 server wich AAC and "suggested" protocollib (dev 403) i upgraded it from a old version that i dont remember. Basically the player crashed, but the console work, and player still here (ghost) and no one can join the server and no errors, i shoul use protocollib dump when it happen?

The server shutdown but i think the issue is still present, if anyone else has more info please do reply!
