Connect failed, more to try #467

Closed vruge closed 10 months ago

vruge commented 10 months ago

one of my colleagues gets the error:

19700101 000000.000 Connect failed, more to try
19700101 000000.000 Could not find client corresponding to socket 3

and finally an exception

MQTT error [-1]: TCP/TLS connect failure

I cannot reproduce the error myself. It works for me. Are there any more options to see more here?

mqtt.cpp-version: 1.2.0

I guess it's more related to paho.mqtt.c. I will create a new issue in paho.mqtt.c
