I got this error using multiplayer mode when i try to login on a server:

registration failed: The authentication servers are currently unavailable

But only on my PC with Win10.

On my laptop with Win 10 it works without any problems.

1. I logged out and in
2. i tried it with and without antivirus and firewall
3. All xbox settings are the same
4. i uninstalled java & the Minecraft laucher and installed it again

How can i solve the problem ?
