Just tried this and it still throws the same error.
I only just bought this NAS. I really hope it's not at end of support already….

Tangentially, I tried the Dropbox one (same process) and it worked.
It'd be nice if there were a MS OneDrive app too. That and Google are the cloud drives I really wanted to access and store here when I bought this NAS.
