Suddenly getting a server error on my instance (self.selfhosted)

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

Where on earth can I even begin to address this?

This is an issue that has been present for a long time but recently came back worse with the 0.19 update. It is caused by lemmy-ui failing to load the site icon and it typically happens whenever the the docker container is started/restarted while you have a site icon set. The only fix at the moment is to manually delete the database entry which contains a link to the site image.

Check this GitHub link for instructions. https://github.com/LemmyNet/lemmy-ui/issues/1530#issuecomment-1605781461

Once I get home from work this afternoon I will post my docker-compose.yml which has an extra container that automatically deletes the database entry then resets it.

EDIT: Here is the extra container from my docker-compose.yml

  icon-fix:
    image: iconfix:latest
    command:
      - /bin/sh
      - -c
      - |
        sleep 10
        # Remove Site Icon - be sure to set your postgres password
        PGPASSWORD= psql -U lemmy -h postgres -d lemmy -c "UPDATE site SET icon = NULL WHERE id = 1;"
        # Refresh Site - replace example.com with your sites domain
	curl -f -sS -H "Host: example.com" http://lemmy-ui:1234 > temp.html
        # Reset Site Icon - Set your postgres password and replace the URL with one that points to your icon
 	PGPASSWORD= psql -U lemmy -h postgres -d lemmy -c "UPDATE site SET icon = 'https://example.com/pictrs/image/2cc85182-5739-4c86-b982-94fc913e80d3.webp' WHERE id = 1;"
    depends_on:
      - postgres

And here is the Dockerfile for building the iconfix image

FROM docker.io/postgres:latest
RUN apt update
RUN apt install -y curl
