Resolution 1: Make sure use the correct username to access backup storage, for example NAS\username.

Resolution 2: The client just join the NAS to their domain, they need to access the NAS using domainname\username.

Resolution 3: Force the credentials renew in Veeam DB. Please follow this post: How to force the credentials renew in Veeam DB

Resolution 4: Run rescan on Repository by going to Backup Infrastructure.
