Why does the redirect of the main page of the site to HostCMS not work?

Question

Apache HTTP Server

The redirect does not work (more precisely, the bare html of the main page of the old site is loaded). I also tried with Redirect 301 and tried to do it by analogy with the http to https redirect, but not a damn thing. On the new site, the urls do not match, so you have to prescribe for each page
. Here is the htaccess code:
