Hey Pete! Any other actions with downloads working or is it all actions that are problematic? Anything interesting in the relay server log files (logfile.txt)? I’m thinking this might be an issue with the whitelist but that message would not be “Pending Downloads”. It would be something like “Failed to process download due to whitelist.”
EDIT: I think the whitelist would prevent the download to the root server completely, so I might be wrong there. I’d have to double check.
