@Keyhan Alizadeh I assume that you are behind the service. It looks like it is already down unfortunately. SSL certificate issues, NIP-05 validation problems, etc. Not bashing by the way - things do go wrong. Plus... I’ve faced attacks in the past just for offering free software and services on Nostr. Imagine if I were actually charging for it. Unfortunate timing for sure. Hopefully, this is just maintenance window or an infrastructure issue rather than a targeted attack.
