ServiceDesk Plus Manual Backup Fail "Exception while trying to fetch configured backup password"

Hi,
I am working on migrating ServiceDesk Plus build 10000 to a new server.
Currently i am running a manual backup, but it is failing with the following logs:

Exception while trying to fetch configured backup password.
Exception while init Backup

BACKUP FAILED WITH ERRORS

Error during backup is :

I have tried changing the backup password to just "backup" and let the scheduled backup complete once, as advised in an old post.
However, the manual backup still fails with the same error.

Does anyone know how i can resolve this?

Thanks in advance.
