Again, about the previous problem with the 8883 port. I was searching and I found that AWS IoT Core changed their MQTT TLS 8883 port for 443 to do the handshake. Doing this they avoid problems in corporate firewalls like the ones I am having: https://aws.amazon.com/pt/blogs/iot/mqtt-with-tls-client-authentication-on-port-443-why-it-is-useful-and-how-it-works/ Do you thing this could be a workaround for issues like mine? If yes, it is possible to change the netmaker source code to implement this?
