MQTT Connect timeout value is ignored #108

Closed frankyfish closed 11 months ago

frankyfish commented 3 years ago

In current plugin version(2.0.2) MQTT Connect timeout value is ignored during CONNECT.

Steps to reproduce: 1) Set some big timeout value image 2) Make MQTT Broker to respond with CONNACK longer than 10 sec (default timeout value for the client)

ER Test is able to connect to the broker even after some of waiting for response (>10sec)

AR Test is failing with a timeout exception, see stacktrace below.

Hi Team,

This issue has not resolved yet for me. I am getting connection drop after 20 concurrency. Please help on this.

Thanks, Vishnu.
