My crewmate and I are experiencing the same thing, I have updated drivers, updated windows, reset router, verified files, checked my clock by clicking it from automatic to manual and back then resetting. I have tried everything I can think of. Still getting one of the two Allmondbeard or Hazelnutbeard errors. We both play via steam on pc, two completely separate households, but seem to get disconnected at the exact same time regardless. We even tried going solo on two seperate servers and were disconnected at the same time. If anyone can help, it would be greatly appreciated.

I have the same issues, and can't seem to find a solution. I can't figure out what the change could've been and any advice would be greatly appreciated.

Well Hazelnutbeard is the "we think you are using rubber banding your controller or using a macro to try and stay connected so we are going to kick you" error... So.......

Sorry for you, i dont know any solution apart from what you can find in the forums.
What kind of errors do they symbolize?

Probably the support is the best adress for this issue.
Could it be an issue with win11 ?
