MQTT Disconnect and Reconnects at very short intervals

Hi,

I am using mqtt client with mosquitto broker. I am facing an issue, client disconnect disgracefully and reconnect immediately, often 5 time in hour some time more than 5 times in hour, i am connecting to broker with unique id with persistent session. My internet is stable.

Disconnection and Reconnection

Screenshot 2021-04-27 230053

my connection code is as following:-

** Future _login() async { // With await, we are assured of getting a string back and not a // Future placeholder instance. client = MqttServerClient.withPort(Constants.serverUri,this.topicpart, Constants.port); // Turn on mqtt package's logging while in test. client.logging(on: true); /// Set auto reconnect client.autoReconnect = true;

/// If you do not want active confirmed subscriptions to be automatically re subscribed
/// by the auto connect sequence do the following, otherwise leave this defaulted.

client.resubscribeOnAutoReconnect = false;

/// Add an auto reconnect callback.
/// This is the 'pre' auto re connect callback, called before the sequence starts.
client.onAutoReconnect = onAutoReconnect;

/// Add an auto reconnect callback.
/// This is the 'post' auto re connect callback, called after the sequence
/// has completed. Note that re subscriptions may be occurring when this callback
/// is invoked. See [resubscribeOnAutoReconnect] above.

client.onAutoReconnected = onAutoReconnected;

/// Add the unsolicited disconnection callback
client.onDisconnected = _onDisconnected;

/// Add the successful connection callback
client.onConnected = _onConnected;

/// Add a subscribed callback, there is also an unsubscribed callback if you need it.
/// You can add these before connection or change them dynamically after connection if
/// you wish. There is also an onSubscribeFail callback for failed subscriptions, these
/// can fail either because you have tried to subscribe to an invalid topic or the broker
/// rejects the subscribe request.
client.onSubscribed = _onSubscribed;
client.onSubscribeFail=_onUnSubscribed;
client.pongCallback = pong;
var lwt = {};
lwt["tid"]=this.topicpart;
lwt["type"]="lwt";
lwt["value"]="0";
final MqttConnectMessage connMess = MqttConnectMessage()
    .authenticateAs(Constants.user,Constants.password)
    .withClientIdentifier(this.topicpart)
    .keepAliveFor(60) // Must agree with the keep alive set above or not set
    .withWillTopic('flutter_test/'+topicpart+'/lwt') // If you set this you must set a will message
    .withWillMessage(jsonEncode(lwt))
    //.startClean() // Non persistent session for testing
    .withWillQos(MqttQos.atLeastOnce);
   // .withWillRetain();
print('client connecting....');
client.connectionMessage = connMess;

/// Connect the client, any errors here are communicated by raising of the appropriate exception. Note
/// in some circumstances the broker will just disconnect us, see the spec about this, we however eill
/// never send malformed messages.
try {
  await client.connect(Constants.user,Constants.password);
} on Exception catch (e) {
  print('EXCEPTION::client exception - $e');
  await MqttUtilities.asyncSleep(5);
  if(client!=null)
  client.disconnect();
  client = null;
  return client;
}

/// Check we are connected
if (client.connectionStatus.state == MqttConnectionState.connected) {
  print('client connected');
} else {
  /// Use status here rather than state if you also want the broker return code.
  print(
      'client connection failed - disconnecting, status is ${client.connectionStatus}');
  await MqttUtilities.asyncSleep(5);
  if(client!=null)
  client.disconnect();
  client = null;
}
return client;

}**

You are using autoreconnect so the behavior you are seeing is expected, the client will reconnect on any disconnect.

You say your internet is stable, that may be so but your network connection to the broker doesn't seem to be, note that stable for browsing is not the same as stable enough to be connected to a broker permanently. I my experience wifi is usually a problem here.

Your unique id with persistent session has no bearing on network issues.

I'd need a full log output of a disconnect/reconnect sequence, its possible your broker is telling you why you are being disconnected.

You need client logs or broker logs?

Client logs definitely, broker logs would be good if possible.

how can i store mqtt client logs in local db or storage is there any option in this package ?

Logging just outputs to the console, if you want to store the logs just re direct your std out to wherever you want it.

You have any plan to enhance package to store package logs in local storage. It will help to test production app through these stored logs.

No, no one has ever asked for this. If you wish to submit a pull request for this I'll gladly look at it. Bear in mind the client runs in both server and browser environments so you will need to find a solution for both.

These are logs from client and broker. It seems broker making disconnect after keepalive interval if you are not publishing anything. when i keep publishing data this is not happening. I tried with 60s, 30s, and 20s keepalive interval but all results are same.

All OK so far, we now send a ping request within 20 seconds -

I/flutter ( 9767): 1-2021-05-03 16:06:58.648442 -- MqttConnectionHandlerBase::sendMessage - MQTTMessage of type MqttMessageType.pingRequest I/flutter ( 9767): 1-2021-05-03 16:06:59.012432 -- MqttServerConnection::_onData - message received MQTTMessage of type MqttMessageType.pingResponse

We now do not need to send another ping request until 16:07:18, however this doesn't seem to happen so we get this -

broker - 2021-05-03T15:07:30: Client 1004 has exceeded timeout, disconnecting. I/flutter ( 9767): 1-2021-05-03 16:07:32.308561 -- MqttConnectionBase::_onDone - calling disconnected callback

So the client is not sending a ping request on time, I will look at this.

What happens if you turn off keepalive?

I set keepAlivePeriod to 0 then i check logs. It was constantly making pingRequest. Is this correct behavior? Following are logs

Keep alive of 0 should disable keep alive, so the client shouldn't send any ping requests, I'll look at this. Has your disconnection problem gone away? The broker should not now be disconnecting you for keep alive purposes.

yes broker is not disconnecting with keep alive 0 but client making instantly ping requests to broker it should not happen. I am waiting for you response regarding keep alive. Because i want to use 60s keep alive.

I'll look at both these but its going to need a code change so you will need to upgrade to the latest package version when I've done this.

ok i am waiting thanks

Hi @shamblett any progress ?

I need to reproduce why in your case the client stops sending ping requests, this may be lengthy, however fixing the keep alive to be disabled when a value of 0 is used is straightforward, I 'll fix this so you can at least run your system without keep alive and re publish the package. At the same time I'll add extra logging in and around keep alive to see what's going on better in this area.

This will be ready when its ready, it may be end of this week or early next week, unfortunately maintaining these packages is not my day job, its done in my spare time like most OS development so there are no timescales for any of this.

Hi @shamblett

If client publishing data then keepalive also continuous to make ping request. It should be make ping request when client not publishing data anymore.
I mean to say if client publishing data then keepalive period should reset and wait for client stops publishing data. Am I correct?
If I am correct then why client making ping request if i am publishing data before keep alive interval.

From the MQTT 3.1.1 spec -

The Keep Alive timer, measured in seconds, defines the maximum time interval between
messages received from a client. It enables the server to detect that the network
connection to a client has dropped, without having to wait for the long TCP/IP timeout.
The client has a responsibility to send a message within each Keep Alive time period. In
the absence of a data-related message during the time period, the client sends a
PINGREQ message, which the server acknowledges with a PINGRESP message.

If the server does not receive a message from the client within one and a half times the
Keep Alive time period (the client is allowed "grace" of half a time period), it disconnects
the client as if the client had sent a DISCONNECT message. This action does not impact
any of the client's subscriptions. See DISCONNECT for more details.

In practice we don't stop sending ping requests if the client sends a control message, we just send them all the time, the broker just responds with a ping response. So if the keep alive period is 20 seconds we send a ping request every 20 seconds regardless of when the last control message was sent.

Package re published at version 9.3.0. Extra logging now in place so we should be able to see better what is happening, please re test.

thanks buddy I will check now.

Hi I tried 9.3.0 version with keepalive 60s. It's getting disconnect after ping response received. This happen randomly not fix duration pattern mostly happen when phone are not in use means phone is idle.

Looking at the above -

21:27:30.2720 (info) flutter 1-2021-05-09 21:27:30.269159 -- MqttConnectionKeepAlive::pingRequired - restarting ping timer

The pingtimer is restarted at 21:27:30, so we would expect it to expire at 21:28:30 or thereabouts, but we get this -

21:29:02.8880 (info) flutter 1-2021-05-09 21:29:02.884331 -- MqttConnectionBase::_onDone - calling disconnected callback

So nothing happens until 21:29:02 when the broker disconnects. It looks as though the app has somehow suspended itself so the timer doesn't expire but it still responds to purely external events such as the disconnect coming from the network.

'This happen randomly not fix duration pattern mostly happen when phone are not in use means phone is idle.' Not sure what this means, what do you mean by idle?

Drop the keepalive to 5 seconds and run your app but keep it active, get the log from this, you should see ping request/responses every 5 seconds, then allow it to go 'idle' as you call it, see if it stops.

I can't see this being the client, it doesn't happen in the VM and no one else has reported this problem, something in your environment is stopping the ping timer expiry.

I'm having this exact issue. However I don't see anything related to ping in logs.

Funny thing is, it was working fine like a month ago and nothing really changed, same old Flutter and library version.

I just upgraded Flutter and this library to latest, still the same.

I just see this line and get disconnected. Nothing about ping in any logs. How should I debug this?

I/flutter ( 5205): 1-2021-05-26 11:58:05.559120 -- MqttConnectionBase::_onDone - calling disconnected callback

'Funny thing is, it was working fine like a month ago and nothing really changed..' well, if it suddenly stopped working something must have changed somewhere. You won't see any ping info in the logs unless you have keep alive enabled on the client. Your only recourse is to look at your broker logs and see why its disconnecting you.

Thank you for the swift response. I don't operate the server but I'll try to get logs from there as well.

I just enabled keep alive and reconnect:

  client.autoReconnect = true;
  client.keepAlivePeriod = 60;

But again no pings. Below is logs from part of the loop that it gets into. Do you see anything suspicious?

Here are some logs:

These seem to be on the stack when disconnecting. Can we say that the server is closing the TCP connection? Btw, MQTTExplorer receives messages just fine when connected to the same topic.

You are reconnecting from auto reconnect then immediately disconnecting for some reason when the client tries to re subscribe -

Try disabling auto resubscribe on auto reconnect.

Try disabling auto resubscribe on auto reconnect.

That was it! Thank you @shamblett! Sorry @Husnain-Asharf if I hijacked your thread.

Auto re subscribe should work, please check that the MQTT version you set on the client matches your broker version, particularly if your broker is a 3.1.1 broker.

Well, spoke too soon. After a while we get back into this loop. Also the code I said that worked is not anymore, oddly (second log below).

ok I'll check the 3.1.1 thing thanks.

Just for the record, 3.1.1 did not change anything here. I'll keep working on it to see if I can do anything.

You need your broker logs, it should show you why you are being disconnected

Here's what my problem was: all my clients had the same client id. Giving unique client ids to clients solved it. I believe that when I connected, there was some other client running somewhere else that made me drop immediately. Thank you so much @shamblett for all your help and for this great library.

hello, my problem is same, it was caused by same client ID, but I can change client ID since every thing boundled with this ID.

And it's unique along with device, How can I check if the client IS REAL connnect or just offline but server side think it was online? (My client seems already stopped, but server still says it's connect)

Hello, I am encountering the same issue. When another user is logged in, it continues to connect to the broker and drops messages. Even though I am generating a random string and passing it as the clientId, it still presents the same issue. Has anyone found a solution?
