Hi all, I’m having some trouble getting a website working with the Cloudflare proxy turned on.
With the proxy on I get a 522 error.
With the proxy off (DNS only) I’m able to connect to my site.
My site is self hosted using windows server IIS.
I have a static IP address that I’ve added to the A record for Cloudflare.
I have set up SSL using “Full(Strict)” mode and Cloudflare generated certs.
I have up IP restrictions in IIS to allow Cloudflare IPs as per the below list and deny all others.
https://www.cloudflare.com/en-au/ips/
Two things I thought might be causing this are:
- Incorrect SSL configuration
- Incorrect IP filtering
Could incorrect SSL configuration be an issue? I’m not sure how to verify it.
As mentioned, I’ve configured IP filtering as per Cloudflare’s list, but I noticed when pinging the domain that the IP returned is not in the list. Could the Cloudflare list be incomplete?
Otherwise, what else could be causing this?
Thanks.
