it's been happening for a while. Not sure when it started but i'd say a few months but only had a bit of time recently to start to poke around and take a look at it.
since posting i've been having issues with my BE - looked like the boot SSD was having issues so new ssd, reinstall i hoped might fix - no luck, issue still occuring.

any pointers for debugging this? cant find a way manually trigger or configuring logging options to investigate whats going on. theme download failure seems to happen early in the process so i'm thinking a corrupt file, unmet dependancy, DNS or firewall type issue.
