After I updated my Veeam infrastructure (Veeam B&R 9.5.0.1536), all my jobs go in failed state. All jobs are related to Windows Server with Exchange server.

As far as I understand, the job failed because of this request over the public key. I tried this KB: https://www.veeam.com/kb1813
Still failed
I have no idea at this moment what could cause this. Can you please log a support case and post the case ID here (and the follow-up after working with our engineers)? They will be able to get much more information out of the logs
