Solution

At first we were clueless on what to do, but later there was a hint in the iot-village channel that asked us to search iot+mosquito for leads. Trying that out we got to know that the port supported mqtt protocol. So we wrote a python script to connect to it and patiently(took more than 20 minutes) waited for the flag.

import sys
import paho.mqtt.client as mqtt
 
def on_message(mqttc, obj, msg):
    print(msg.topic+" "+str(msg.qos))
    print(msg.payload)
 
mqttc = mqtt.Client()
mqttc.on_message = on_message
 
mqttc.connect("209.97.159.20", 1883, 60)
mqttc.subscribe("#", 0)
mqttc.loop_forever()
