Never tried to debug websockets before, but at least relay.orangepill.dev looks reasonable

["OK","7604fef7067a081a2271876212df761042ea9208b91c08a38b86b2507300d299",false,"blocked: pubkey not admitted"]

Interesting I don't see this "OK" message in nip-01 but coracle understands it so it's probably specified elsewere. (Who thought "OK" was a good code for a fallible response? lol)
