I don't know what I may be doing wrong, as I have little knowledge of linux. I'm trying to add Cloudflare to the server. The domain is already working on Cloudflare, but I can only open it with port 8920 at the end of the address (https: //****.com: 8920). If I type only the address does not open and if I type with port 443 it also does not open. I thought the solution was port forwarding, but I did as I saw on the internet, but to no avail My server is in Debian.
