502 Bad Gateway (Cloudflare) when using WordPress REST API

The error might be originating from Cloudflare’s communication with your origin server.

  1. Check the Cloudflare dashboard for any outage or issues reported.
  2. Cloudflare usually provides a brief description or code with their 502 error page.
  3. Ensure your origin server is running and accepting connections. A 502 error can occur if Cloudflare can’t communicate with your server.
  4. Check your server’s error logs. They can provide more specific details about why the server might not be responding. Look in /var/log/nginx/error.log
