Redirect from HTTP to HTTPS looping?

Question

htaccess

I tried three redirect options, I tried it in the site config, htacccess, it's the same everywhere. Namely, an endless redirect from https to https, provided

RewriteEngine On
RewriteCond %{SERVER_PORT} !^443$
RewriteRule .* https://%{SERVER_NAME}%{REQUEST_URI } [R,L]

While when entering https ://example.com - everything is fine

Answer 1

If "everything is fine when entering https://example.com ", then the redirect redirects the browser to the wrong place.
Of course, you should look at the site itself or try it yourself through the "Developer Tools - Network" to see - somewhere there must be differences - or www appears / disappears somewhere, or something like that.
