I’m having an issue on this module as well, however it’s not the same issue as the original poster. The issue appears to be certificate related. In the training it walks you through steps to fetch a certificate which I was able to follow however the EMS is saying this certificate is invalid, I’ve tried all three certs from the certificate tree and they all produce the same invalid certificate error. Here is the screencap, the bottom lines repeat until the window is closed.
I was able to get around this issue by adding a logger to the JSON, not sure why this parameter has an impact on the EMS connecting successfully or not but here is my JSON contents, the only difference between the failure I showed above and the successful connection is the addition of this logger. In this example certifications validate is set to false, this setting still would fail to connect.
“appKey”: “#ENTER YOUR APPKEY HERE#”,
