DNS Resolution Problem with Traefik and Parse Server

Parse Server 📡
1

Hello everyone,

I’m experiencing an issue with the configuration of Traefik and Parse Server. I’ve set up Traefik to route requests to my Parse server, but I’m receiving a DNS_PROBE_POSSIBLE error and sometimes a timeout when trying to access my service via the domain name.

Configuration Details:

  • Traefik Version: v3.2.1
  • Parse Server Version: latest
  • Domain Name: parseserver.myurl.com
  • Traefik Entrypoint: websecure on port 443
  • SSL Certificate: Configured with Let’s Encrypt via myresolver
  • Routing Rule: Host(parseserver.myurl.com)
  • Middleware: HTTP to HTTPS redirection

What I’ve Checked:

  1. Traefik logs do not show any obvious errors.
  2. The SSL certificate seems to be correctly configured.
  3. DNS is set up to point to my server’s IP address.
  4. Ports 80 and 443 are open on the server.
  5. I tested direct access to the IP, but the issue persists.

Logs and Error Messages:

  • Deprecation warning in Parse Server logs: DeprecationWarning: The Parse Server option 'encodeParseObjectInCloudFunction' default will change to 'true' in a future version.
  • HTTP 200 response when accessing http://172.28.0.3:1337/parse/health directly from within the Docker network.
