Hello,
We developed a BASIC script that sends tag data to an Azure IoT hub using MQTT, and it has been working flawlessly in most of our devices. However, we have one 3G device that does not seem to be able to connect. I believe this has to do something with the 8883 port, because I was able to run the test script provided here that sends data to the Ewon MQTT Broker and that works fine. Any idea what might be causing this issue? Like I said, we have been successful in other sites with 3G, and the settings should be the same on the ewon.
I tried using the information provided here - eWon Flexy over 3G MQTT connection fail
but was not successful.
Thanks,
Yoni
