Fix PHP Laravel Issue

PHP server exposed subscribe events for client(Frontend) that continuous listen frontend
final client = MqttServerClient.withPort("broker.hivemq.com", "", 1883);
Using above url with port exposed by Server

Problem: Server not sending subscribed event response on frontend.

Event subscribed from frontend
client.subscribe('new_ride_request_' + sharedPref.getInt(USER_ID).toString(), MqttQos.atLeastOnce);
client.subscribe('ride_request_status_' + sharedPref.getInt(USER_ID).toString(), MqttQos.atLeastOnce);
