Update: I can now get it to generate the content, after spending some time on relays (I was being lazy about this at first). However, I do still get the error message as in the screenshot above (failed to reserve domain name). I have an idea of something to try and will post back.

Hi the issue is with relays - please choose some relays for this new profile and make sure those relay lists are saved on nostr, how to do that depends on the app you're using. We can't find your relays and then can't send you one-time login code and can't load your content and then can't publish your site event.
