Could it be because I don't have an account set up?

You don’t need an account set up. nostr.build has a free tier for any npub.
Hmmm it works fine for me. Can you try again? Maybe it was just an intermittent issue with nostr.build. Also, how did you login on my site? Nip-07 ext? If so, which one?
If you signed in with a public key, that would explain why it doesn’t work. I just removed that option from the nostr-login modal.
Maybe because I have used up my nostr.build free privileges?
Just tried making a new account, and I just get a spinning "connecting, establishing connection to your key storage" notification.
I'm not aware of a total limit for free accounts. You need to accept the nsec.app connection request. If you're on iOS, there's special instructions https://nsec.app/ios.html. It's much easier to use a nip-07 extension though. I use nostr:npub1tnpfz60snm7ler8k8c69335n37we6690qttl88t556yzkjxhahjq3kkkpe on iOS.
No limits for free usage, just the file size.

https://nsec.app should work, but I haven’t tested
