Switched from S3 to Glacier. Everything seemed to be backing up fine but once it hit 4.4GB uploaded all further files display the error "attempted to perform an unauthorized operation" as the message on the History tab of CBB Server edition. I need to get past this error and would appreciate any suggestions. I see all of the folders in Backup Storage tab but around 85% of the files are not uploaded.

Source server is WS2019.
