It seems to be for me, but looking for confirmation.

Any app (Interstellar, Thunder, Summit) doesn't.

I haven't tried another network or vpn.

If I try to load in browser, I get this error:

Error!

There was an error on the server. Try refreshing your browser. If that doesn't work, come back at a later time. If the problem persists, you can seek help in the Lemmy support community or Lemmy Matrix room.
