Hi I'm trying to set up a modded server for me and my friend but when I join I get the error: Internal Exception: io.netty.handler.codec.DecoderException: java.io.IOException: Packet 0/26 (SEntityStatusPacket) was lager than I expected, found 162 bytes extra whilst reading packet 26 The server says "Server out of date!" and "Incompatable Vanilla sever" I only have one mod installed called Immersive Portals version 0.4 (the latest version I can download) My friend can join the server but when I try to it gives me the error. I've tried reinstalling the server, removing the mods, reinstalling forge on the server, and restarting the server. I have forge version 34.1.0 for 1.16.3 and so does the server. My friend has the same forge version and the same mods. Me, my friend, and the server all have the exact same
mods and version of forge. How do I fix it?
