Re: [paho-dev] Correct way to recover from broker disconnect?

Hi Ian,

    It seems to have something to do with the SSL socket.  I can reconnect fine if I don't connect using OpenSSL.

Jimmy,

the right way is to call MQTTClient_connect, as you seem to be doing.   You don't need to create another client object.

Are you using the latest client code?

Hello,

I am using the paho C client over ssl to connect to a mosquito broker.  In tests when the broker is restarted the client disconnects but I am unable to reconnect to the broker by simply calling the MQTTClient_connect routine.  What is the best way to reconnect to a broker that goes down?  Am I missing an interim step? Do I need to create a whole new client handle before trying to reconnect?

I am getting the following errors when trying to reconnect using the same client handle that just got disconnected:
