Subject: AsyncClient: How to get connection failure reason

 

Hello Dev,

 

We are using async_client of ‘paho.mqtt.cpp’ library.

 

After calling connect() API if connection doesn’t go through, is there a way to know reason of failure ?

 

There could be multiple reasons why connection may not go through 1) Remote IP not reachable 2) TLS certificate mismatch etc.

I am looking for an API/callback which can tell what went wrong after calling connect API on async_client.  

 

Regards

Pankaj
