Hello,
We apologize for the issue you are facing while trying to connect your Rank Math account. A Cloudflare error 520 typically indicates that the server is returning an unexpected response to Cloudflare’s requests. Here are a few steps you can take to troubleshoot this issue further:
-
Check Firewall Settings: Ensure that your server’s firewall is not blocking Cloudflare’s IP addresses. You may need to whitelist Cloudflare IPs to allow proper communication.
-
Review Server Configuration: Since you mentioned that there are no errors in your nginx logs, double-check your server configuration to ensure that it is set up correctly to handle requests from Cloudflare.
-
Disable Plugins: Temporarily disable other plugins on your site to see if there is a conflict causing the issue.
-
Contact Hosting Provider: If the problem persists, it might be helpful to reach out to your hosting provider for assistance, as they may have more insight into server-side issues.
If you continue to experience difficulties, please reply to this ticket, and a human agent from the Rank Math Support team will assist you further. Thank you for raising this concern!
