we assume that the issue might be related to the firewall. However, we would like to confirm that the firewall is configured correctly, and PostgreSQL is also properly installed.

Additionally, we would like to provide further information related to the documentation:

Port 80 successfully redirects to port 8069, but when we attempt to connect through port 8072, it does not redirect as expected — which appears to be the cause of the issue. once we cancel the worker the module is working perfectly one we reinsert the number of workers inside our niguix it's shown with a message lost connection.

Hi,

Your custom POS module's issue with offline kitchen printing, where port 8072 isn't redirecting and canceling the worker resolves it, likely stems from firewall rules or the worker process itself. Verify that your firewall allows inbound and outbound traffic on port 8072, and examine the worker's code for network connection issues, resource limits, or threading problems.

While less likely, check PostgreSQL configuration and Odoo's configuration file. Review your custom module's code for port binding and error handling. Test connectivity with telnet and analyze network traffic with tcpdump. Focus on the worker process and firewall rules as the primary areas of investigation.

Hope it helps
