Is it possible to find out the real IP of the server protected by CloudFalre?

Question

cloudflare

The site is on a free plan, proxied through CloudFlare. Tell me, is it possible to find out the real IP of the server?
If yes, can it be fixed and how?

Answer 1

Some time ago I saw in a clud proxy error message that the site does not respond to such an ip, and so it was not from the local network, so I can assume that such a configuration option is possible and it can burn your address, at least this is a testing method.
And so, there is no universal way, for each site you need to look for vulnerabilities, mainly these are attempts to make a network request from the server to the attacker's machine.
