Backup Agent Windows - Since latest update can't access share

[Dolphin]

Since I have updated Veeam Backup Agent to v. 3.01.1039 the scheduled backup job will fail to run throwing an error as the share is not accessible "Backup target for <nas-name> is not available".
We did not change any settings on server side (Windows 2012 R2), although some Windows updates could have spoiled settings?
Also editing job settings won't load folders/share list anymore:

Hi Dolphin,

Looks like a permissions issue. Could you please try to specify the credentials?

Thanks

Ok, I really don't remember if those credentials fields were ever set

UPDATE: It worked! I must assume the update removed the credentials and I didn't remember that the agent required this! Thanks!
