I am trying to send a testing value to AWS IOT Shadows but when I upload it to my device it keep saying "Cant Setup SSL ConnectionTrying to send Data". please help me to send this value to AWS IOT Shaodws! I have tried to change the ARN to HTTPS end point ARN.. and keep getting this error messages.

{
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED)

    delay(500);
  }
}

  Serial.print(shadow);

  char* result = iotClient.update_shadow(shadow, actionError);
  Serial.print(result);

  delay(10000);

please help me ! Thanks

setAWSDomain() expects an API endpoint, not an ARN.

Here is an example.

To find the API endpoint, select the device in the console by going to IoT > Manage > Things > ThingName > Interact and find the HTTPS endpoint.

Alternately you can use the describe-endpoint command from the AWS CLI.
