Suddenly getting a server error on my instance (lemmy.world)

I don't know when it started, I usually check my instance through the Voyager app and it never showed a problem, but I'm suddenly getting "server error" and 502 bad gateway errors on my instance on desktop. I haven't made any major changes (read, any at all) since I last confirmed it worked on desktop.

Checking the logs I don't see any obvious proxy issues but I am getting weird connection issues in lemmy-ui:

TypeError: fetch failed

lemmy-lemmy-ui-1  |   }

Where on earth can I even begin to address this?

So...it's working now? I haven't touched anything yet, but I just checked my instance again and it works perfectly fine on desktop now. It always worked through Voyager, so I was able to let people know there was an issue. If it comes back I'll try some of these suggestions to find a more permanent fix.
