.htaccess CNC will work on autosubdomains?

Question

htaccess

Good afternoon. I'm trying to make a simple way to CNC links on autosubdomains. Added a
.htaccess file
with the content
RewriteEngine On
RewriteRule ^(.*)\.html$ index.php?id=$1 [L,QSA]
but redirects don't work and the domen.site.ru autosubdomain is generally unavailable with this code.
subdomain in folders is www/site.ru/domen/
