Hi thanks for the amazing guideline I've read #2 and #3 but still facing rc=-2 problem as below

August 2020 - Saturday 07:48:05 16:48:04.955 -> Getting IoT Hub host from Azure IoT DPS 16:48:15.020 -> Starting IoT Hub connection 16:48:25.205 -> ---> mqtt failed, rc=-2 16:48:37.233 -> ---> mqtt failed, rc=-2 16:48:49.262 -> ---> mqtt failed, rc=-2 16:49:01.284 -> ---> mqtt failed, rc=-2 . . .

Hi , thanks for the suggestions in #2 and #3 , they worked for me, except iotc_scopeId is name for oithubHost in configure.h .

So at line# 316 in mkr10x0iotc.ino I commented out these 3 lines and added iothubHost = iotc_scopeId;

// char hostName[64] = {0};
// getHubHostName((char*)iotc_scopeId, (char*)iotc_deviceId, (char*)iotc_deviceKey, hostName);
// iothubHost = hostName;
iothubHost = iotc_scopeId;
