Hi I'll give the brief rundown of this error I've been having. No clue how to fix it.
Running forge 1.18.2 with compatible mods that work, I've tested everything in singleplayer and there was no issue at all. The server is able to start up with all the same mods, I've checked the files everything matches. The server is able to start up just fine but no one could enter it. We all received the same error message:
Internal Exception: io.netty.handler.codec.EncoderException: java.lang.IllegalArgumentException: unable to fit 2532363 into 3
