Failed to upgrade VM components: Unable to reinstall deployer service: SSH credentials are not specified

[AlexLeadingEdge]

Hi guys,

Just upgraded to Veeam B&R version 13.1.1.18 and I'm getting this error message when it tries to auto-update the guest components. This guest is Windows Server 2008 R2.

Code: Select all

24/08/2026 10:37:33 am Failed REDACTED: Failed to upgrade VM components: Unable to reinstall deployer service: SSH credentials are not specified (0:00:04)

- VBR upgraded to 13.1.1.18 (Build 20260812) on 20 August.
- Server is Windows Server 2008 R2.
- Veeam Agent for Windows is 6.3.2.1205 and cannot be upgraded to 13.1 on that OS.
- Veeam Installer Service successfully upgraded to 13.1.1.18.
- Veeam Data Mover / Backup Transport remains at 13.0.1.2067.
- Components Update specifically says Veeam Data Mover service requires an update.
- The attempted update fails in ~4 seconds with:
- Unable to reinstall deployer service: SSH credentials are not specified
- This is a Windows machine and VeeamDeploySvc is the Windows Veeam Installer Service, so SSH makes no sense.
- Use persistent guest agent is disabled.
- We removed the old Veeam Guest Agent 13.0.1.2067, and the same failure remains.

Hi Alex,

As it's a technical issue, open a Support case and allow Veeam Support time to review the debug logs. We cannot meaningfully troubleshoot such issues over the forums, so start with a Support Case.

The behavior indeed does not sound correct, but not immediately aware of any known issues so support case is the way to go.

Please share your case number once created, thanks!

Hi David,

Is it possible to get this case escalated to someone who knows what they're doing? The current Veeam Technician I'm dealing with seems to be incompetent.

Hi @AlexLeadingEdge,

If you have concerns on the handling / processing of the case, use the Talk to a Manager button from the case portal; that will connect you directly with Support Management who will review the case and allocate additional resources as needed.

As I see it, the case was closed at your direction, but not quite following on what the solution was. Regardless, the Talk to a Manager button is always the way to go if there are concerns on the case.
