This issue concerns the self-hosted sync server (git hub dot com/ankitects/anki/tree/main/docs/syncserver).

After the update to 24.11, the healthcheck endpoint should work. However, building using the provided Dockerfile or the docker hub images (hub dot docker dot com/r/jeankhawand/anki-sync-server) creates a healthcheck endpoint that still returns unhealthy no matter what.

I was able to fix it making the following change to the Dockerfile:

```diff
- HEALTHCHECK --interval=30s --timeout=10s --start-period=5s --retries=3 \
- CMD wget -qO- http://localhost:${SYNC_PORT}/health || exit 1
+ HEALTHCHECK --interval=30s --timeout=10s --start-period=5s --retries=3 \
+ CMD wget -qO- http://0.0.0.0:${SYNC_PORT}/health || exit 1

```

Perhaps this is due to my configuration, but it may be worth documenting this possible fix it if not done already.

My configuration:

- Anki sync server running in docker
- Nginx running on Ubuntu 24.04.1 LTS host (not containerized)

`docker-compose.yml`:

```yml
services:
  anki-server-sync:
    build:
      context: .
      args:
        ANKI_VERSION: 24.11
    image: anki-server-sync:latest
    environment:
      SYNC_PORT: 5805
      SYNC_USER1: ***:***
      SYNC_USER2: ***:***
    ports:
      - 5805:5805
    volumes:
    - ./syncserver:/home/anki/.syncserver
    restart: unless-stopped

```

Dockerfile: see change above relative to the source file (git hub dot com/ankitects/anki/blob/main/docs/syncserver/Dockerfile)

Nginx config:

```nginx
upstream anki-livesync {
        server 127.0.0.1:5805;
}

server {
        listen 443 ssl;
        server_name ***;
        ssl_certificate cert/domain.cert.pem;
        ssl_certificate_key cert/private.key.pem;
        ssl_protocols TLSv1 TLSv1.1 TLSv1.2 TLSv1.3;
        ssl_ciphers HIGH:!aNULL:!MD5;

                location / {
                        proxy_pass http://anki-livesync;
                        proxy_set_header Host $host;
                        proxy_set_header X-Real-IP $remote_addr;
                        proxy_set_header X-Forwarded-for $remote_addr;
                        proxy_set_header X-Forwarded-Proto $scheme;
                        client_max_body_size 100M;
                }
}

```
