Adding DataDomain repo incorrect user

[gmajestix]

Hello,

I have a DataDomain 3300 with OS 6.1.2.30-615547 and Veeam 9.5 with Update 4. When trying to add a deduplication device I instantly receive an error saying Invalid user credentials. This user is assigned a backup operator role on DataDomain and is enabled for DDboost. Username works to login to DataDomain SSH and web console. I went through the logs Svc.VeeamBackup in C:\programdata\Veeam\Backup and saw this:

Any ideas on this matter or should I just open a ticket?

Yes, please, this will be more effective.

I managed to solve it. On DataDomain in Allowed clients the server was defined without FQDN. You can see this in DataDomain CLI using command "log view debug/messages.engineering".

For example.
