I successfully installed OpenMQTTGateway on the ESP8266 NodeMCU CP2102 ESP-12E. I configured the WiFi settings and can ping the IP. But the WebUI doesn’t seem to be open and I can’t connect. The port isn’t even open or listening. It does connect to my MQTT server (outboard) but nothing about to connect inbound.
I’m using the web install and tried a number of NodeMCU configurations. They all work but have the same WebUI problem.
Any idea what is going on here?
