Backup directory not found using Ola DatabaseBackup

I was executing the backup using the service “Domain\SQL.BACKUP” to the shared directory, but I end up with the below error message always. This service account is different from that of the Agent Service account. The directory exist and the account I am trying to use has FULL CONTROL over the directory and subdirectories. I tried with sa and other accounts too but still it is failing.

I tried providing the local backup path, it throws the directory exists but I give the directory check from SSMs, it fails. For security reasons, I have b

locked the share path.

Please advise.
