Clone Jobs failing - NW 9.1.1.3

Hello,

OS - Windows Server 2008 R2

2 - NW Servers - 9.1.1.3

2 - Backup Repository Data Domains DD670 OS: 5.6.2.0-543944

We Clone backups to the data domain to each office. Over a MPLS network (50MB).

Cloning was working fine prior to upgrading to 9.1.1.3. We were on version 8.2. The failures at this point seem to be random. Some days jobs will clone and other days they will not. Error Message I am receiving below.
