Ahh, but why does it work ok on other inbox relays?
The NIP42 auth is done automatically by default. The problem is that relay ask for authentication after you send an EVENT or a REQ.
After successful authenticaltion, the REQ is automatically resent but not the event (yet). I wrote a possible workaround here: https://github.com/rust-nostr/nostr/issues/509

Forget this. It's an issue on all inbox relays that are doing auth properly. ðŸ«
Any ideas on how to fix this properly in the rust-nostr? I'm happy to help on this but want to know what you've already explored or thought about before I start looking into it.
Should be fixed here: https://github.com/rust-nostr/nostr/pull/667
