I am using cloudeFlare as a DNS service to all my websites using sub domains please look at the image below,
I have a problem that I cannot solve, I have an machine with an IPv4 (who except connections from 0.0.0.0/0 and runs on port 80) that always return 522 when accessed from cloudFlare, using the IP in the url or using curl works without issues.
I do not understand why doesn’t the “A” records works ? I am sure that the server does not block cloudflare.
can someone please help?
