Ugh! I can't get it to work and I have no idea how to diagnose. Can @greenart7c3 can help? I do notice this error in the logs but I was able to load the url in the browser fine, so not sure what's up there. Using Graphene OS and ntfy.

Try force closing the app and opening it again. Try enabling tor If none of that works change the notification type to connect directly to the relays instead of using the push server
