Showing Error 521: Web Server Is Down

Hi all,

Getting Error 521: Web Server is Down

I think Cloudflare is unable to make a TCP connection to the origin web server. Should I wait for it or have to do some troubleshooting.

Do you see logs on your origin server showing connections being blocked? If so, then you need to unblock Cloudflare’s IPs so connections can be made.
