I can't login to a server.
This is the error message i get - Internal Exception: io.netty.handler.codec.DecoderException: java.io.IOException: Bad packet id 84
Minecraft and server version : 1.12.2
The server is vanilla with plugins and i'm the only one who can't join it.
Joining other servers works
I have already tried to reinstall minecraft, updapte java and use vpn but it didn't work.
Thanks for your help
If other servers work then the issue is with that server and only the server admins can help.
Solved, i just entered wrong port ip. Sorry
