Failed Client Backup, Why?

I have a Windows 11 client running 2.5.23, that will fail on both file and image backups and I don’t know why. I moved the client to another Urbackup server to see if the problem was the client or the server and the client failed to complete a backup on the second server as well. No idea why.

That’s why for the file backup. Either fix the read error or enable “Do not fail backups in case of hash mismatches or read errors” in the advanced settings.
