Hi Ahmed,

Here is the response from our nRF Cloud team

The client id they are using is what is autogenerated by the app and is not in AWS.

it looks like they are wanting to just view device info, ("MQTT broker for accessing device information") so they should probably use an "account device" type.

The CreateAccountDevice REST endpoint should be called to create the account device and obtain the credentials.

example:
curl --location --request POST 'https://api.nrfcloud.com/v1/devices/account' \
--header 'Authorization: Bearer <API_KEY>'

the response is JSON containing the account device ID and cert data.

{
    "clientId": "account-851bd211-a22d-4276-9226-bb621228b4f3",
    "caCert": "-----BEGIN CERTIFICATE----- ... -----END CERTIFICATE-----\n",
    "clientCert": "-----BEGIN CERTIFICATE----- ... -----END CERTIFICATE-----\n",
    "privateKey": "-----BEGIN RSA PRIVATE KEY----- ... -----END RSA PRIVATE KEY-----\n"
}

from there, create a PEM file for each credential... the newlines (\n) will need to be removed.

use the client id from the JSON and select the "self-signed" certificate option and select the three PEM files

.

I got

[quote userid="77062" url="~/f/nordic-q-a/98998/nrf-cloud-mqtt-broker/422041"]"Client network socket disconnected before secure TLS connection was established"[/quote]

in two applications. In both "MQTT Explorer" (the one recommended in your course) and MQTTX

Hello,

From where did you try to connect to the MQTT broker? Where do you get the message "Client network socket disconnected before secure TLS connection was established"?

Thanks

Kind regards,
Øyvind
