koji problem

[Zoltan Kota]

Hi,

My build of pybliographer for devel yesterday around 21:00 UTC failed 
with the result:
"BuildrootError: could not init mock buildroot, mock exited with status 
30"

http://koji.fedoraproject.org/koji/buildinfo?buildID=65374

I tried to resubmit the job without success. Is it a buildsys issue or my 
fault?

And now I cannot login to Koji, it says:
"Could not establish an encrypted connection with koji.fedoraproject.org 
because your certificate has been revoked."

What to do with this? Could anybody help?

Thanks!
Zoltan
