I have configured a sub-domain to my IP address, and it works fine when it is configured as “DNS only”.
But, when I change it to “proxied” (for blocking DDOS attacks) - I cannot reach this site!
What can I do for solve it?
Are there any logs of cloudflare that can I check?
(I’ve already checked the logs of my server. There is no any information about any request that came)
Did you place the port on purpose? If you are trying to access port 801, that won’t work on Cloudflare. You’d either need Spectrum or Cloudflare Tunnel.
