Hii,
To fix real-time kitchen display updates over HTTPS in your on-premise Odoo:
Edit your Nginx config:
location /longpolling {
proxy_pass http://127.0.0.1:8072;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header Host $host;
}
*In your odoo.conf file*, make sure:
proxy_mode = True
longpolling_port = 8072
Restart services:
sudo systemctl restart nginx
sudo systemctl restart odoo
i hope it is use full
