The nginx reverse proxy creates it's configs automatically and just forwards the requests to wp_web (IIRC).
Problem:
How to fix the redirect loop? Everything else seems to work. I also have other containers running and accessible via domain2.com without any problems.
Thanks in advance ;)
回答1:
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.
