Please excuse me, I have little experience in setting up web servers, so I’m asking for help. There is server A and server B of an Apache web server, there is domain.com (server A) and sub.domain.com (Server B). There is a white IP that forwards to domain.com. How to make a config correctly to open a subdomain via https
On server A there is a config for forwarding the subdomain to server B
<VirtualHost *:80>main domain config here
<VirtualHost *:80>
