Every time we try to enable the proxy on one of our sub-domains, we cannot access the website.
Hey there @alibre
Error 522 indicates that Cloudflare is unable to establish a TCP connection over to your origin server. Here’s a step-by-step guide to troubleshoot:
- Check your server’s firewall settings to ensure it’s not blocking Cloudflare’s IPs.
- Verify that your hosting provider isn’t experiencing any issues.
- Ensure your web server is running and there are no network issues.
- Confirm that Cloudflare’s IP addresses are allowlisted on your server.
For more detailed instructions, please refer to Cloudflare’s community tip on fixing Error 522: Community Tip - Fixing Error 522: Connection timed out.
That being said, could you please provide a domain name and a record that is facing the issue? If this is also persisting, could I please have you open a Support ticket and provide the ticket number here for further investigation.
