Problem Description

Issue

Internal Exception: io.netty.handler.codec.DecoderException: net.minecraft.ResourceExceptionLocation: Non [a-z0-9/._-] character in path of location: minecraft:\u0001\u0001\uFFFD\u001A

What does this mean? Its only one person having this issue. Everyone else is working perfectly

Reproduction Steps

  • Added mods
  • loaded up MC
  • tried to connect to server
  • Connection failed
  • Sent error message

That error sometimes indicates that the client doesn’t have the same mods as the server (or the same mod versions in rarer cases)
