Backup to NAS always fails. License Issue?

I have Acronis Backup & Recovery 11 Server for Windows + Universal Restore

I am backing up to two "Vaults"
1. An External Hard Drive
2. A Network Drive (Synology NAS)

I have two different backup plans, one for the External Hard Drive, and one for the Network Drive.

The plan for the external drive always executes and completes no problems, it is flawless.

The plan for the Network Drive always fails with the error below. I can go to "vaults" and explore the Network Drive with no issues, and checked my network credentials many times over. It will do a full backup to the network drive when I newly create the backup plan, it just subsequent backups fail.

I am starting to wonder if my license only allows 1 "Vault" to be a backup.

Any help is appreciated, this is my first time working with this product.
