Why does the browser see the subdomain as a section of the site (accessed through a slash)?

Question

htaccess

I have three sites hosted at /home/www/ that I administer in WordPress. Through the admin panel of the host, I started making a test subdomain for one of them (site2.com) in order to transfer a copy of this site there using Duplicator. The admin created a subdomain in the form of a folder: /home/www/site2.com/test and put index.html there.

The problem is that I can't open this index.html in the expected way: test.site1.com/index.html (or https, doesn't matter). It opens like this: https://site2.com/test/index.html, which doesn't work very well for me.

Interestingly, I have already made such a test subdomain on one of these sites, and it opens normally: test.site1.com/index.html,the only thing you need to make sure that http without s is mandatory. I got into the htaccess of the problem site, there is such a stray, is it not the case?:

RewriteEngine on
RewriteCond %{HTTPS} !=on [NC]
RewriteRule ^(.*)$ https://%{HTTP_HOST}/$1 [ R=301,L]

Can you tell me how can I solve this problem?

Solution: I had to comment out one more line from the bottom and top, and everything worked.

IfModule mod_rewrite.c tag
RewriteEngine on
RewriteCond %{HTTPS} !=on [NC]
RewriteRule ^(.*)$ https://%{HTTP_HOST }/$1 [R=301,L]
tag /IfModule tag

Answer 1

Is the virtual host registered in the web server config?
The subdomain is also registered in DNS, does it return the correct IP address?
