Hi I’m pulling my hair out over this problem and made some progress, but I’m stumped with why the Mosquitto broker is rejecting the connection from my ESP switch device, stating socket error, see log:

I have no idea what the ip 172.30.32.1 is, but the 192.168.1.143 is the device I’m trying to connect.
Any help greatly appreciated
Edit: From the ESP8266 serial port I get this:
WiFi connected
IP address:
192.168.1.143
