Azure agent in DPM "The current operation failed due to an internal service error"

Hi

I am using agent 2.0.9028.0 with DPM 2012 R2 4.2.1417.0 and am having a lot of problems.

First of all, every time you reboot the server the Azure backup agent loses its registration information so you have to re-register it again.

Then jobs fail with this error:

"The current operation failed due to an internal service error [0x7DD]. Please retry the operation after sometime. (ID 100066)" 

Any ideas on what may be happening?

Thanks.
