trying to login i get a "bad request"

[Peter Boy]

I’m trying to login into wiki as well as pagure.io without suggest. Yesterday it worked fine, today in the morning I had to try 2-3 times, than it worked. But now I’m out of luck.

If I try to log in into pagure I get: https://fedoraproject.org/wiki/Server

If I try to login into wiki I get 
https://id.fedoraproject.org/login/gssapi/negotiate?ipsilon_transaction_id=0...

And after filling in name and password:
https://id.fedoraproject.org/openidc/Continue?ipsilon_transaction_id=04
400 - Bad Request
User not authenticated at continue

Any idea what is going wrong?

Thanks
Peter
