Problems

If wp-login keep redirecting

If you are behind a reverse proxy, add this to wp-config.php before the last require_once :

/** reverse proxy */
if ( (!empty( $_SERVER['HTTP_X_FORWARDED_HOST'])) ||
     (!empty( $_SERVER['HTTP_X_FORWARDED_FOR'])) ) {
    $_SERVER['HTTPS'] = 'on';
}

or if that don’t work, add directly at the top of the file :

$_SERVER['HTTPS'] = 'on';
