Live Query: Not receiving Events on iOS Client. Our Parse server hosted on Azure App Services.

[bluelabeldeveloper1]

Issue Description

We have hosted Parse server on Azure App Services. We are able to connect to live Query and able to Subscribe to it. We are getting below messages.

2019-01-01 19:03:26.917094+0530 LiveQueryTest[59625:972922] ParseLiveQuery: Sending message: {"clientKey":"xxxxxx","op":"connect","sessionToken":"","applicationId":"xxxxxx"}
2019-01-01 19:03:27.285251+0530 LiveQueryTest[59625:972922] ParseLiveQuery: Received message: {"op":"connected","clientId":5}
2019-01-01 19:03:27.388337+0530 LiveQueryTest[59625:972922] ParseLiveQuery: Sending message: {"query":{"className":"PostQuestionMessage","where":{"type":2}},"requestId":1,"op":"subscribe"}
2019-01-01 19:03:27.600455+0530 LiveQueryTest[59625:972813] ParseLiveQuery: Received message: {"op":"subscribed","clientId":5,"requestId":1}

And we are subscribed to Update Event but when we updated any records we are not getting event Back.

On the server:

We tried to listen to Specific port "1337" as below: Every time we do that our Parse Dashboard and API stops working. So Is it necessary to listen to specific port i.e "1337" or var port = process.env.PORT || 1337; will also work for Live Query.

var httpServer = require('http').createServer(app);
var port = 1337;
httpServer.listen(port, function() {
console.log('Parse Server running at ${port}');
console.log("The value of port is " + port); 
});
ParseServer.createLiveQueryServer(httpServer);

Expected Results

We should get the event update as per our subscription.

Actual Outcome

Not receiving event updates as per the Query Subscribed,

No, it's not necessary! You can specify whatever port you like! You have to make sure though that Azure knows what ports need to be open for inbound traffic... (parse-server's default ports are 1337 parse & 4040 dashboard) Azure may disable all open ports by default for security reasons.

In case you're hosting your db in a separate machine, you need to declare mongo's port (27017) as outbound from parse-server and inbound from mongo-server.

Now if you still have problems, you should show your whole index.js to allow us be more helpful!

@bluelabeldeveloper1 can you provide the configuration part for liveQuery? Did you configure the class names you want to listen to accordingly?
