Whenever I click "Backup now" in the Backup GUI, the smaller "Back Up" window opends, and after a while I get the following error message:

I use Rackspace CloudFiles as a storage backend, last backup was 3 days ago (successful. I have not changed any settings since then.


EDIT
It seems that the cause for this problem is network difficulties, for some reason I can't connect to one of the CloudFiles backend servers via HTTPS, and therefore it falls back to IPv6 for some reason and since I'm not IPv6 enabled, it fails. I have yet to find the cause for this network issue.

EDIT #2
The issues is now resolved, it might have been solved by a router restart.
