If you haven’t made any configurations, nostr-relay-tray receives all kinds of events.
Discussion
The relay receives the event as I see the kind 1 counter in the relay tray dashboard go up when I post from runstr, however the note does not display in any clients so the relay seems to have an issue serving the runstr notes up to the clients.
I tested using jumble.social and amethyst, couldnt see the notes in either client when posting a runstr event to my relay tray.
Jumble only fetches events from your write relays. So, if you want others to fetch events from your local relay tray, you can use the proxy feature of the relay tray to obtain a public address. Then, set this public address as your write relay, and make sure it is as high-priority as possible, since clients usually only use the first 2 to 4 relays.
