Connecting Gravity TEL0180 to mosquitto MQTT

I am trying to connect a Gravity TEL0180 wifi module connected to a SCI DAQ to a mosquitto MQTT broker running on a Raspberry Pi, rather than Siot version 1, Siot version 2 or EasyIoT.  I configured the TEL0180 with the SSID and password for my local Wifi and the LED does go from white, to blue, to red indicating that it is getting through to the wifi and that it has successfully loaded the configuration.  But I never get a steady yellow indicating that it is connecting to the MQTT and I never get the purple light at all. Instead, I get a green color that stays on for about 10 seconds, blinks, and repeats. The SCI DAQ is set to send data every 5 seconds.

I configured the TEL0180 with the MQTT IP address, user name and password and I put a zero into the Save field. I put five lines of topic data named sensor/dac, sensor/ambient, sensor/object, sensor/temp and sensor/humidity.  I assumed that the Siot1 and EasyIoT were the most likely to be similar to a simple MQTT like mosquitto.  

The mosquitto MQTT is configured to accept connections on port 8883. I tried adding a port modifier to the IP address, but that didn't help. I have a subscriber running as a daemon on the raspberry pi and it successfully reads messages sent to the mosquitto MQTT from publishers on the raspberry pi and from my workstation over the network.

How can I troubleshoot to see what is going wrong with the SCI DAQ connecting to the MQTT via TEL0180?
