i cant login to Skyblock or any server at all!

it says:
Failed to login:invalid session(try restarting your game and the launcher)

i had this problem many times from time to time and it always work to restart the launcher and minecraft

now it does not
i have logged oyt my acount also but nothing

 

Fixed for most people, try again

 

wuut now it worked
i tried so many time but now...
mojang problem?

 

Yes it was, the issue is fixed for the most part now

 

If this happens again, you can always go into the Minecraft Installer and "Fix Game" rather than "Install". That often works for me.

 

thank you
