mojang auth servers seem offline
im getting
ERROR Task failed: "Authentication operation failed due to a network error: Error downloading https://authserver.mojang.com/refresh - server replied: Internal Server Error (299)"
and
Error downloading https://authserver.mojang.com/refresh - server replied: Service Unavailable: Back-end server is at capacity (301)"

 

Yeah, it is giving me the same message no matter what pack I try to launch

 

i just got a session token...keep retrying

 

I will

 

After what i can see its because mojang has some launching problems. There is no clues about corrupted chunks etc in the crash-report.
