      Hi, I'm having problems connecting to multiplayer servers. 
      Immediately when I try to connect to a server (or a few seconds after connecting to the server) I get kicked with one of the following messages:

      • Internal Exception: io.netty.handler.codec.DecoderException: java.util.zip.DataFormatException: invalid code – missing end-of-block
      • Internal Exception: io.netty.handler.codec.DecoderException: e: Loading NBT data

      • Internal Exception: io.netty.handler.codec.DecoderException: java.util.zip.DataFormatException: invalid code lenghts set

      I am on java edition (PC), in 1.8 or 1.9 (the servers I am interested in are 1.8/1.9). 
      I've already tried uninstalling/reinstalling Minecraft, restarting my PC. Nothing changes. 
      On the web I found several people with similar error messages but no satisfactory answers.
      Can you help me? Thank you in advance.
