Hyper V Backup suddenly not working

[mklima]

Hello,
since yesterday the backups of our Hyper-V Host dont work any more. I have several other jobs, Agents, another Hyper-V - that all works just on this host it is almost directly failing.

Error 09:23:01 09:23:45 0,0 B 0,0 B 0,0 B 0:00:43 Unable to allocate processing resources. Error: Mindestens ein Fehler ist aufgetreten. (One or more errors occured)

Thats all i am getting. Even on the server itself i dont get any logs about errors or warnings for the failed backup tries.

After some tries, i found out that my issue is about making Hyper-V Cloud Backups from this specific maschine. All other kind of jobs included cloud VM backups from another maschines are working.
The Off-Host-Proxy wont work, i just get an error if i force to connect over it, im not sure if the On-Host one works...
So at the moment im stuck i cant make any backups from the Hyper-V to Cloud, its aborting with error.
