Fiz o cadastro com minha chave mas a url https://nip05.asnubes.art/.well-known/nostr.json?name=carloshmbtn não traz nenhum registro. Exemplo da minha verificação atual: https://carloshmbtn.github.io/.well-known/nostr.json?name=carloshmbtn. Você está aceitando somente o formato npub no cadastro, segundo https://github.com/nostr-protocol/nips/blob/master/05.md a chave deve ser sempre no formato hex, se você faz a conversão dela desconsidere isso.

I described all process. If you add your "NPUB" the system will convert it into HEX. There are a lot of text describing the process. By the way, if you dont use a npub the process do not finish.
In other hand, to manage your names, before registering yours npub, you should register ith a user and pwd for using on nip05.asnubes.art
thank you for let me now
You can watch how the app convert your npub key into hex here-> https://nip05.asnubes.art/public/js/key.js also if you are using hex key there are more probabilities that you are sharing your pirvkey instead of your pubkey in an error
by the way, if the process doesn't work it shows you an error when adding.
