Question

Domain is a Subdomain:

https://en.example.com

# Begin Force SSL
RewriteEngine On
RewriteCond %{SERVER_PORT} !^443$
RewriteRule (.*) https://%{HTTP_HOST}/$1 [R=301,L]
# End Force SSL
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress

Make sure that you define the WP_SITEURL and WP_HOME at wp-config.php

define('WP_HOME','https://yourdomain.com');
define('WP_SITEURL','https://yourdomain.com');

And add this condition to check if the https at wp-config.php

    if ( isset( $_SERVER['HTTP_X_FORWARDED_PROTO'] ) && 'https' == $_SERVER['HTTP_X_FORWARDED_PROTO'] ) {
        $_SERVER['HTTPS'] = 'on';
    }
