Current problems with Jerboa

I started using Jeboa about a day and a half ago, no problem. It defaulted to lemmy.ml rather than lemmygrad.ml. No problem as I was browsing anon just to see how I liked the app.

Now, when I open the app, nothing is loaded, and changing from local to all still loads nothing.

Is this a problem with lemmy.ml? How can I change instances.
