device to cloud using (MQTT) self signed certificate

[DEN_CIL]

Hey there,

I'm trying to test the Azure IoT Hub. MQTTBox is used for testing. I have generated certificate.pem and key.pem from openssl. Command used is

1. openssl req -newkey rsa:2048 -nodes -keyout key.pem -x509 -days 365 -out certificate.pem – to generate a new private key and public certificate

i have used certificate.pem on client certificate section and key.pem on client key file.

MQTT client id = TESTUSER

protocol = mqtt/tls

HOST is iothubhostname.azure-devices.net:8883

ssl/tls certificate type=self signed certificate.

username=iothubhostname.azure-devices.net/TESTUSER/api-version=2016-11-14

passowrd= none

but the connection error occurring .

i have created the device on Azure web portal using fingerprint of the certificate.pem

• is the command for generating certificate and key is correct?
• no need to add any file on CA file option?
• is a need to fill the user name option?
• is the procedure for doing is correct or is there any steps missing?

PSlease don't refer to any site because I already checked that.
