Server unavailable error



I have some trouble connecting my device.
The error message i get tells me that server is unavailable. But i can connect with MQTT explorer.

$DBG072:23060:7 MQTT: AWS MQTT Connect Error: -39

My device doesn’t support username and password. Only certificates.
I have enabled SCI authentication for this particular client.

As for the rootca i have followed the following link.

Thank you in advance


Sorry for the message. I got it working.
On the device I got the client id wrapped in qoutes.
