Ayush,
Can you please post some code snippets or provide more context regarding your source code?
There is a MQTT guide located here that covers creating a MQTT client and server, as well as details on MQTT brokers. Make sure your code looks similar to the example program, and if you still have problems, report back with some more detailed code snippets.
