Message not sent form

Hi,

I have a website built with Brizy.

The website is https://sg.openrainbow.com

I use a reverse proxy to host it on https://voice.openrainbow.com/sg

When I send a message with sg.open… it works well.

When I send a message with the website on the reverse proxy, it does send the message but I get a “message not sent” notification.

Any idea how to fix that ?
