Hello All
I managed to succesfully connect to iot-core, receive config and publish telemetry.
But only after 5-6 some times more failed attempts.
Device panics, restarts, tries again...finally connects if it's lucky.
Any idea why?

device - wemos mini esp12f
esp8266 version 2.5.2
latest versions of mqtt and iot libraries.

I think I had a similar problem and adding a disconnect before connecting helped, let me know if that works for you.

 if (!mqttClient->connected())
  {
    mqttClient->disconnect();
    ESP.wdtDisable();
    connect();
    ESP.wdtEnable(0);
  }

I decoded the stack trace if that helps;
