I wrote it with the help of a translation. Sorry for the typo. My English is not very good.
Also, after putting cloudflare in front of the VPS, the IP address of the server is masked. There is no problem here.
However, the outgoing request from the server shows the ip address. “https://iplogger.org/” does the job of exposing the IP address very well.
If this is due to misconfiguration it would be great to know how to fix it.
An end-to-end guide will help many people.
Respects.
