Same IP for everyone with nginx config

Hi,

When the plugin is running on a server with nginx, the IP stored is always the same // something like 127.0.0.1… ($data[‘ip’] = $_SERVER[‘REMOTE_ADDR’]; doesn’t take the real user IP).
It’s a problem when we set up the limit of appointments per day per user, because the IP is the same for everyone : if the limit is 1, nobody can book an appointment after the first booking.

Maybe?https://docs.php.earth/faq/misc/ip/?and?https://packagist.org/packages/symfony/http-foundation?helps ?
