The DNS change worked for me !
Worked cheers. Is that a permanent fix for the given issue ? I'm with BT ( UK ) were they the problem ?
Complete uninstall, reinstall fresh, deleted .minecraft folder. Reinstalled GPU driver fresh.
Now says unable to start check your configuration. Clean install nothing else.
Unfortunately it doesn't list it. Even on a new install. There's a 1.16.2 pre1 on Snapshots though. It doesn't connect to realms either.
Worked Ethan thanks. How did you know to try it ? Thanks again.
