Are you trying to login with a NIP-07 web signer installed? What is your signer?
Discussion
I just want to log in with the service I just bought, I'm a stupid end-user.
I click "login" nothing happens ...
I mean... there is zero user guidance here on you page (and many others)
You assume (wrongly) that everyone has the same knowledge about these signers.

in any case, good luck .... I'm not gonna waste my time on this
Basically every nostr login needs a signer available. We need to know your signer name so we can represent the issue and try to fix the bug if there is any. π«‘
that's not the isse man... basic product design and business flow: you guide the user!
that's what's wrong wit nostr: you build stuff for people that already "know"
If you get an address at your site, it doesn't work, ... and you don't even see the issue
can I get a refund on that address I bought? As I can't really use it.....
(kidding, ... but you will get such questions if you ever manage to get real users)
