Numerous network errors

Question

Hi Support team, I enabled Trace, and I see numerous connection errors when the app starts. As a matter of fact, I am getting network errors when I try to download the SDK from your site. Is this something that you are working on? Due to these errors I can not play a game. Here is a sample of logs AppWarpTrace: +[WarpMessageDecoder decode:]...updateType=1 AppWarpTrace: -[WarpClient onNotify:]...WarpNotifyMessage AppWarpTrace: +[WarpMessageDecoder decode:]...updateType=1 AppWarpTrace: -[WarpClient onNotify:]...WarpNotifyMessage AppWarpTrace: +[WarpMessageDecoder decode:]...updateType=14 AppWarpTrace: -[WarpClient onNotify:]...WarpNotifyMessage AppWarpTrace: +[WarpMessageDecoder decode:]...updateType=14 AppWarpTrace: -[WarpClient onNotify:]...WarpNotifyMessage AppWarpTrace: NSStreamEventEndEncountered : 5 AppWarpTrace: Error 0: (null) AppWarpTrace: -[WarpClient onConnect:]..value=0...connectionState=0..sessionId=122185326 AppWarpTrace: Network issue.....

Here is a fresh log that I got a few seconds after I started a game

Hi Vasilis,

 

How frequent are you getting this log? As in the above log, I can see it has come only once which normal case. This can occur due any kind of interrupt which can impact socket connectivity between device and server. Some of the reasons can be an intermittent network, call, any activity on a device which can put it in the background etc.

 

I have performed testing on my iOS Sample and below are the logs:

In the above log, you can see that I was connected to the server around 6 mins then I called disconnect API.

Please let me know if this is not the case.

 

Thanks.

I just noticed that you are using udp. I am not. Could that be the case?

The server has some serious problems. During the game, I got an AUTH_ERROR.
I will try the server on sp

Answer 2

Constantly!!! The logs are full with connection errors. I believe that this is because your sockets are very picky. Can I control them?

If not, my other choice is to resend the message, but, after how many seconds should I try to resend it?

Comments

Can you connect to our other server just for testing? Please use following code to select the server:
    [[WarpClient getInstance] setGeo:@"sp"]; // connect to server in Sao Paulo

You can paste this code just after SDK initialization code and let us know the result. It will help us to provide better support from our end.

---

Sure, I will try it later tonight

---

What is a typical range of times (in sec) for a message to be send to all connected users in a room?

---

If I understood the question then you are asking about how much time it takes to deliver a message to each and every user in the room. Normally, if you are sending message using sendChat API, it is in milli-seconds. However, it also depends on the network strength of user's mobile.

---

Based on your experience / tests, what is the worst and best case scenario?

---

I can not connect to SP. I am getting AUTH_ERROR as soon as the app starts.

---

No difference. I am still getting numerous connection errors

---

Can you share the complete Xcode console logs of 5 mins of gameplay?

---

I did send you an email yesterday with all the logs, which were connection error logs. But,
I think I know what the problem is:
Last night, around 11pm Greece time, I played a game for more than half an hour and I did not have any connection error. This means that you need to update your servers. Do you have a load balancer on the server? Do you add more resources when the demand increases?

---

Thanks for your input. Let me discuss this with my production team. I will get back to you asap on this.

---

Do you have an update?

---

How about now, do you have an update?

---

I have replied to your mail from support. Please check.

Did you receive my reply?
