My client hasn't found your relay list, so it doesn't know where you published your metadata.

Go to Relays > My Relays and set up relays like this:

3-8 relays to write to. Mark as both "write" and "outbox". Don't choose relays that require payment if you don't want to pay.

1-4 relays to read from. Mark as both "read" and "inbox". These definitely can't be paid, or other people can't send you messages.

Tick lots of (all popular working relays) as Advertise.

Tick just a few popular relays as Discover (purplepag.es, nostr-pub.wellorder.net, nos.lol, might be enough).

Then advertise that list by pressing "Advertise Relay List" just once (if you change the list, press it again).

Then later on when I restart my client, it will find your relay list (if any of my discovery relays overlap your advertise relays), then it can find your stuff.
