Cannot connect to server

Hey there,

I cannot connect to my server, I get he following error:

Internal Exception: io.netty.handler.codec.EncoderException: java.lang.IllegalArgumentException: Extrenuous data in: -1

For some reason, when I turn cracked to true I can join.

I don't remember doing or adding anything new. I just got this error out of a sudden.

I reinstalled my server but uppon connecting I get the same error again. My friends can connect without any errors

Even after reinstalling Minecraft I get the same error. I don't understand what's going on

I just tried it. It doesn't work. I get the same error and sometimes it just says "Disconnect" after trying to connect.
Thank you for your help so far!

On PaperMC 1.14.4

I now tried out Vanilla and Spigot. Both let me connect like normal.
After that I tried out Paper again and it now works aswell.

I have no idea what the issue was but it's solved for some reason so thank you very much!
