Hey everyone, I recently took our Veeam Backup & Replication Server (version 12.3.1.1139) off the domain and joined it to a workgroup. Now, while everything else seems to be functioning correctly, I'm having trouble with my PRTG Sensors that monitor my Veeam backup jobs. They're throwing a "401: Unauthorized" error when I try to connect. I've already tried updating the device credentials to the local admin account, but I'm still hitting a wall. Any ideas on what could be wrong or how I can fix this? I'd really appreciate any insights! Thanks!

You might want to check your local firewall rules. Since your Veeam server is now part of a workgroup, the firewall settings might not align with the new network profile. Make sure that the local firewall is allowing access through the right ports for PRTG. Also, try to see if you can connect to the Veeam server with those credentials from another machine, like via RDP or an SMB share.
Have you checked the Windows security events on the Veeam server? Those logs might give you more insight into why PRTG can't connect.
It sounds like your PRTG is still attempting to use domain credentials, which won't work now that your server is in a workgroup. Try creating a dedicated local user account on the Veeam server and update the PRTG sensor settings to use this new account instead. That should help you get connected!
I attempted that but I'm still encountering the same error even with the local admin credentials set up. Any other suggestions?
Creating a local account can be a bit risky since it exposes your Veeam server to external connections with hard-coded credentials. It's better to have agents directly on your Veeam server that report back without needing credentials. Just a thought!
I've already tested RDP from another system and it works fine. The firewall logs are also empty, and since I'm using third-party protection, the settings might not be the issue.
