htaccess https too many redirects works not on specific hosting

Question

I want to force redirect HTTP to HTTPS via htaccess. Of course I looked for a tons of solutions here, but nothing helps. On other hosting this solution works but not here.

If I try it this way:

RewriteEngine on
RewriteCond %{HTTPS} off
RewriteRule .* https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

It will redirect to HTTPs, but then it says the page is not working, TOO many redirects.

But I have nothing more in my htaccess, so why too many redirects?

Another solution that works not:

RewriteCond %{HTTP:HTTPS} !on  [OR]
RewriteCond %{HTTP_HOST} ^example.com
RewriteRule (.*) https://www.example.com/$1 [R=301,QSA]

Here is the dump of $_SERVER:
