When I am playing on a multiplayer server of my friend, I often get kicked from the server with the error messages,
-Internal Exception: io.netty.handler.codec.DecoderException: java.util.zip.DataFormatException: incorrect header check
-Internal Exception: io.netty.handler.codec.CorruptedFrameException: length wider than 21-bit
I have already tried restarting my router, changing my DNS IP, updating my graphics card driver, reinstalling my Minecraft, updating my Java and also updating my WLAN USB stick. I definitely need further solutions. Switching to a LAN connection is unfortunately not an option.
