The received encoded string buffer error

Hello @everyone!

g lost connection: Internal Exception: io.netty.handler.codec.DecoderException: The received encoded string buffer length is longer than maximum allowed (118 > 48)

Does anone know how to fix this?

Does the issue persist if you have at least 4 characters in your username?

Yes, it does. When i had nickname "genium" the same error occurred.

Im also use GeyserMC, can this error happen due to this?
