Minecraft – How to fix Minecraft java.lang.nullpointerexception group error

minecraft-java-editiontechnical-issues

My friend is having a really annoying problem with his minecraft but he doesn't have a SE account so I thought I'd ask this for him: Whenever he tries to log onto a server he gets this message: 

java.lang.NullPointerException group.

We have tried:

  • Reinstalling minecraft(including the .minecraft folder),

  • Reinstalling java,

  • Eradicating everything java related on his PC,

  • Disabling his antivirus,

  • Flushing the DNS cache,

  • signing off and signing in to minecraft,

  • Restarting his PC,

  • Raging 🙁

How can we fix this?

Your problem is already fixed probably, but for the people who are searching for a fix, follow my steps

  1. Search for CMD and run it as administrator
  2. Type in the bar: netsh winsock reset
  3. It should be fixed!
  4. If it still doesn't work, try contacting Mojang, the creators of Minecraft
