Error: Key not valid for use in specified state.

Case #04918346

We are using Veeam Agent for windows. The version of veeam is 5.0.0.4301 and it is working on Windows 10 pro. The error we are getting when trying to do a backup is "Error: Key not valid for use in specified state. "

WE have updated the system and the veeam software, rebooted the machine etc.

Hi Shaunp,

Please, work with our tech support engineers directly to get it sorted as debug logs analysis is required to understand and resolve the issue.

Did you happen to get this resolved? We are having the same error, but Veeam support told us they could not help.

I contacted support about this issue since I couldn't find a forum post answer.

They told me it looked encryption key issue related. I ended up generating a new encryption key to be safe, and ran an active full backup of the affected job. That resolved the errors for me. The old key still works on the old data. So it's a strange issue. That was the resolution I found.
