[Snapshot Pro] Snapshot fail

Hi, I have been trying to create a backup of my site but getting nowhere. I configured and ran snapshot via the dashboard and the hub but neither seems to work. Initially the max execution was being flagged but I set this to an acceptable value. The back up process via the dashboard throws an error (cannot remember what this was), and if you look at the hub it is sitting at 0% with a moving cog indicating that it is doing something. I have granted support access should it be needed.

Many thanks and warm regards
