Hello, I am in early testing of ignition. I am using MQTT Explorer to publish. MQTT Explorer generates urls starting with mqtt://. I have installed MQTT Engine, Distributor and Transmission. So far I have only found options to enter server addresses starting with tcp:// or ssl:// any help would be much appreciated. ---

The hostname is the important part, isn't it? Just copy everything after `mqtt://` and put it into one of the `tcp://` or `ssl://` addresses. ---
