I am facing this error frequently. Sometimes the data gets published as expected but sometimes the UNS transmitter is unable to connect with my MQTT Server. Can someone help me resolve this?
I would suggest you open a support ticket (support@cirrus-link.com) and submit a copy of your Diagnostics Bundle. If that compressed file is larger than about 14MB please go to Contact Support - Cirrus Link Solutions - Worldwide - United States to submit your bundle and answer the questions of versions of Ignition and our modules on this Gateway.

Thanks for the prompt response. I realized that there was an error in my UDT configuration. Some of the tag values were null and hence the transmitter was unable to publish the data over the broker. So, now I’ve instantiated the tag values and it’s fixed and now working for me.
But there’s this thing whenever I do any changes in my transmitter or server the transmission module gets stuck and takes a long time to connect with the broker. I don’t know if this is happening for the trial version of ignition or chariot broker or so, but this needs to be fixed and looked into.
