Janus integration with Azure Event Grid namespace

Hello,
I try to connect Janus to Azure Event Grid namespace for MQTT v5 messaging.

I have some issues and I am not able to connect to Azure namespace.

Some have have experience with that and can provide me some help please?

I use mqtt client for debugging and I succeed to connect when I do not use CA certificate.

But when I try to comment it from Janus mqtt.jcfg it takes default one from OpenSSL. It seems that using the CA cert make the issue.
