When you deploy an application like n8n or OpenClaw from the Hostinger Docker Catalog, it is assigned a default temporary hostname (e.g., n8n-xxxx.srv123.hstgr.cloud). To use your own custom domain (e.g., n8n.example.com) with full HTTPS (SSL) support, you must update the project’s configuration and configure your DNS settings.<\/p>

Step 1: Prepare your DNS (Cloudflare or other providers)<\/h2>

Before changing the configuration in hPanel, your domain must point to your server:<\/p>

    \n
  1. Create an A record for your desired subdomain (e.g., n8n).<\/li>\n
  2. Set the Content\/Target to your VPS IP address.<\/li>\n
  3. Important<\/strong>: If using Cloudflare, set the Proxy status to DNS-only (gray cloud) during the initial setup. You can reactivate the proxy (orange cloud) once the SSL certificate is successfully issued.<\/li>\n<\/ol>

    Step 2: Update the Docker Compose configuration<\/h2>

    You must tell the Docker container to listen for requests coming from your custom domain instead of the temporary one.<\/p>

      \n
    1. Go to your hPanel → VPS → Manage<\/strong>.<\/li>\n
    2. Navigate to the Docker Manager<\/strong> section.<\/li>\n
    3. Locate your active project (e.g., n8n) and click the Manage
      \n\"\"
      \n<\/strong><\/li>\n
    4. Then access the .yaml editor<\/strong>.\n

      \"\"<\/p><\/li>\n

    5. Locate the labels section in the YAML file. Look for lines mentioning Host rules.<\/li>\n
    6. Change the default hostname to your custom domain in the following places:\n
        \n
      • traefik.http.routers.[project-name].rule=Host(‘yourdomain.com’)<\/li>\n
      • traefik.http.routers.[project-name]-secure.rule=Host(‘yourdomain.com’)
        \n\"\"<\/li>\n<\/ul>\n<\/li>\n
      • Deploy the container to apply the changes.
        \n\"\"<\/li>\n<\/ol>

        Step 3: Verify SSL and Connectivity<\/h2>

        Once redeployed, Traefik will automatically attempt to issue a Let’s Encrypt SSL certificate for your new domain.<\/p>

          \n
        1. Wait 1–3 minutes for the SSL handshake to complete.<\/li>\n
        2. Open your site in an Incognito\/Private window to avoid cached errors.<\/li>\n
        3. If you encounter an ERR_TOO_MANY_REDIRECTS error, ensure your Cloudflare SSL\/TLS encryption mode is set to Full (strict) or that the Cloudflare proxy is temporarily disabled.<\/li>\n<\/ol>

          By updating the Traefik Host labels in your Docker configuration, you can easily transition from a temporary development URL to a professional custom domain. This setup ensures that your Docker applications remain secure with automated HTTPS certificates.<\/p>

           <\/p>

          \n

          Notes<\/strong>:<\/p>\n

            \n
          • SSL Renewal:<\/strong> If you use Cloudflare proxies, you may need to briefly disable them or restart the Traefik container every 3 months to allow SSL certificates to renew.<\/li>\n
          • Port Conflicts:<\/strong> Do not change the internal container ports unless you are an advanced user, as this can break the reverse proxy routing.<\/li>\n
          • Backups<\/strong>: Before making changes to your YAML configuration, it is highly recommended to create a VPS Snapshot as a recovery point.<\/li>\n<\/ul>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
