Log into Qobuz outside of Roon and figure out what the issue is. Are you trying to use a free Qobuz account? Set up Qobuz within Roon using your email address that you used in Qobuz.
EDIT: Then login within Roon @ Roon - Settings - Services - Qobuz - Edit
You probably want to remove your email address from these screenshots, this is a public forum
