If you have a domain with hosting and you want to verify your #Nostr account with that, you can try my tool:

NIP-05 Creation Tool

The tool generates a .zip file.

Inside you have a .htaccess file for your Apache server and a folder which contains a JSON called "nostr.json".

You simply need to paste the unzipped contents in the hosting linked to your domain.

You will get something similar to what I have here!
