Yeah I tried for a bit to make it work with mutiny but was unsuccessful.
Something about the way their relay handles the events for the nwc flow.
I will come back to trying to make it work before next release.
Correct, I'm using https://github.com/benthecarman/nostr-wallet-connect-lnd and with my own lnd node and works well with Amerhyst (even with orbot).
I'm using the mutiny relay for NWC.
Discussion
The NIP for ephemeral events (incl. some used in NWC flow) was recently updated, not all relays respect that. Some SDKs expect the new behavior, which leads to weird bugs when using older non-compliant relays.
See more details here: https://github.com/rust-nostr/nostr/issues/164#issuecomment-1786049227
To be backward compatible and handle both types of relays, make sure to not expect an "OK" response after sending an ephemeral event.
