Redirect loop when https

I added ssl-certificate on my Joomla web-site. My actions:

1. Add certificate data to hosting
2. In configuration check SSL for entire site
3. In configuration.php rewrite live_site as https://mysite.com

And it's all good, web-site work with https, but I need to redirect site from http to https when user enter. For this I add to .htaccess next rule

RewriteCond %{HTTPS} !=on
RewriteRule ^ https://%1%{REQUEST_URI} [R=301,L]

And after this I have an redirect loop error.

I tried different variants of rewrite rules in htaccess, but nothing help. Need an advice please.
