[Spacewalk-list] All repo-syncs failing

[Peirce, Dean]

Hi all, 
All of my repo updates have stopped working for some reason. I’ve checked that all of the external sits I’m syncing with are valid, and the worked successfully for a long time.
I ran one sync manually and this is what’s in the repo-sync err file:

2021-04-07 13:15:56,568 [Thread-505] ERROR com.redhat.rhn.taskomatic.task.RepoSyncTask  - Traceback (most recent call last):

Any help is much appreciated.
