add_action( 'init', function () {
if ( is_ssl() || ( defined( 'WP_CLI' ) && WP_CLI ) || wp_doing_cron() || empty( $_SERVER['HTTP_HOST'] ) ) {

// Many proxies and load balancers terminate HTTPS and pass this header instead.
if ( isset( $_SERVER['HTTP_X_FORWARDED_PROTO'] ) && 'https' === strtolower( (string) $_SERVER['HTTP_X_FORWARDED_PROTO'] ) ) {
