There is a good chance that one of your relays has gone away. This seems to happen quite frequently, and we don't have a good mechanism to steer people to "good" relays in a simple manner. Guessing it is "nostr-01.bolt.observer" in your case.

Good point, thanks. I spent some time working on profile, but not on the relay lists. I'm going to spend some time on that next.
Also working on making that easier... https://primal.net/e/note1ftyhhwsk2tvy5wsgq4vjh47aen0nfrkrk27wdnzgl2t47lqacfjs5ulm4c
