I keep getting an error saying that my MQTT transmission client failed to achieve connected state. Though, I am using same settings along with the username and password to connect with my MQTT Engine from other client and that connection is working.  
I am having issues with this particular MQTT transmitter.  
Any help will be appreciated!

Caused by "Connection timed out".

That's purely a network error. If ping works, then look at any possible firewalls along the network path.
