Too many redirects with reverse proxy

wordpress docker docker-compose jwilder-nginx-proxy redirect-loop

Like @Damocles stated, there has to be

$_SERVER['HTTPS'] = 'on'; in wp-config.php. The standard configuration

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

seems to be not enough.
