FYI: coracle upon connection instantly sends two REQ's:

["REQ", "REQ-82764758", {kinds: [1], since: 1681967605}]

and

["REQ", "REQ-81775670", {kinds: [1], since: 1681946005, until: 1681967605, limit: 20}]

To which an NIP-42 AUTH requiring server sends back 2 NOTICE's of failure (even though the server sent an AUTH challenge upon connect)

It responds to the AUTH challenge properly though.

The client should probably first use NIP-11 to get the supported NIPs - see that it supports 42, and then expect an AUTH challenge?

Nostr not having formal client initiated connect/auth makes this a little awkward.
