Why getting a 400 bad request

[brunofvalli]

I think I got the system up and setup with MQTT I am debugging the code and not using the Docker container.

Watching Wireshark I keep getting a "Client Hello" and then the application is responding back with 400 Bad Request.

What am I doing wrong? I have put break points around the code, but I don't think it is the code responding back. Is there something that is going on behind the scenes that I am not seeing?

PS: Debugging this thing is really fun, since each try takes about 5 minutes. It must have been hell the code this.
