Hi,

Today I upgrade in my homelab (with NFR license) from Veam 12.3 to 13. I have 3 Proxmox node and three Proxmox backup job, Everything was running fine before the upgrade.

 

Now with 13 I discovered that Proxmox is missing, when I click “add new server” and virtualization platform Proxmox is not there.

 

Proxmox plug in is installed version 13.3.1.7

 

No idea what has happened with the upgrade. The upgrade process ran without an issue.

 

Any idea?

 

What I already did is uninstall the Veeam Proxmox plug-in and reinstalled installed after a restart of each step.

Hello ​@Edy!

Please take a look at this KB article and check if you're affected by one of these issues: https://www.veeam.com/kb4687

Well I can select a client and get paid support. It’s probably the easiest way.

That's certainly not the way to go and a violation of the EULA 🤓

    That plugin should work as it is the latest version. Not sure about this one, as a support ticket I think is the best route to take to get support to help get it fixed.

      How do I open a support ticket with a NFR license?

        You would select community edition and it is best effort support.  I thought you had paid support.

            That might work.

                Thank you this KB article helped. I had to generate a new certificate. Mine was from 2018.
