Tried to do #NIP-05 verification of nostr account recently. Some experience:

https://thebitcoinmanual.com/articles/nostr-account-nip-05-verified/ helped to understand.

https://nostr.directory/ - did not work, still don't know why. Might be my mistake.

https://nostrverified.com/ - did not work, no promised message after 3 days.

https://iris.to/ - verification done in a minute. Nice job, #[0]
