Hi @ZadokZeePriest -

Were you able to resolve this? Curious how you did if so.

Hi @ZadokZeePriest -

Just following up again to see if you were able to add your Host to Veeam?

I was facing the same problem invalid credential error.

Now issue resolved while id use. \administrator

Thanks….

Based on my experience, Windows Server 2022 requires Veeam 12.
