I have been having problems with Veeam community edition failing to complete backups and giving the error “Application is shutting down. Unable to retrieve next block transmission command” at different points in long running backups. This happened for local backups as well as remote system backups (on my network). This error was from Veeam 12 although 11 was having consistent issues as well. I tried new backup repo hardware, a new motherboard/USB controller, all the drive/os fixes/scans...there are no 3rd party antivirus scanners, and tried checking for volume snapshot errors.
What seems to have fixed it is explicitly blocking all internet traffic (outbound) for the Veeam server executables. What could my local backups have to do with the internet? I have a fairly complex set of internet firewall rules with MiTM cert inspection, so I’m not surprised if Veeam gets unexpected certificate errors or failures to reach servers in background processes, but would it affect my local backup reliability?

+22Have you tested v13? V12 is still valid but you may find that v13 works better due to enhancements. Unsure why you need to block the Internet unless there is something specific Veeam is doing. If v13 has the same problem I would open a support case to investigate.
+23I have never heard of such behavior before
We really aren’t “support” here and thus don’t have access to what all error messages can mean within Veeam’s product line. That said...a brief search and I found a similar post from a few mos ago:
Walk through the steps/process this user went through to see if you see anything similar causing your issue.
Keep us posted.
Thanks, I had seen that post and I guess in order to test that, I would have to undo my fix which will try.
About going to Veeam 13, I don’t want to lose reverse incremental.
