Hi there,

Error 520 indicates that your server is returning an unknown error to Cloudflare. To troubleshoot this issue, follow these steps:

  1. Temporarily disable Cloudflare by clicking the orange cloud icon in your DNS settings, turning it grey, which bypasses Cloudflare’s proxy and allows you to see the error directly from your server.
  2. Check your server’s error logs for any clues about the error.
  3. Ensure your server is properly configured to accept HTTP/HTTPS requests from Cloudflare’s IP addresses.
  4. Contact your hosting provider for assistance if the error persists.

Remember to re-enable Cloudflare’s proxy by clicking the grey cloud icon, turning it back to orange, once you’ve resolved the issue.
