I am using ESP32 development kit and SIM800L V1 and I am trying to connect to Azure IoT Hub. I am using self-signed X509 certificate without a CA certificate. The module connects to network and to the apn succesfully, but still unable to connect to the mqtt broker. I keep getting error "MQTT_CONNECT_UNAVAILABLE" (rc = 3).
