Why does the output change when using HTTPS and HTTP?

Question

Nginx

Good day everyone!

I’m working with a site on Bitrix (It’s so by the way) on one license 2 sites (This is conditional for description, in fact there are more of them)

Now I’m working on the 2nd site, I noticed the following, if you open it via HTTP, it opens what you need.

If you open it via HTTPS, then the content from the first site is displayed.

The essence of the question, do you need to configure the SSL certificate or turn on the toggle switch somewhere in Bitrix?

Also for information, on the Bitrix server, spinning on httpd and nginx, the BitrixVM virtual machine is not there.

Answer 1

You need to set up the environment. Bitrix is ​​not to blame here.
See the config of your webserver that listens to https

Answer 2

I'm wildly sorry, what kind of configs are these?

Answer 3

Virtual Host settings for Apache, more precisely what is written in the DocumentRoot when listening on port 443
