AWS IOT reconnect issue after the browser tab goes idle for a while

[aarthi-mallow]

I am using AWS IOT for the socket connection. Below is the code which connects the client to the AWS IoT. Everything works fine until the browser tab becomes idle for a while.

initMqttClient = ->
  mqttClient = AWSIoTData.device(
    region: AWS.config.region
    host: "<%= ENV['MQTT_HOST'] %>"
    clientId: 'mqtt-client-' + (Math.floor((Math.random() * 100000) + 1))
    protocol: 'wss'
    maximumReconnectTimeMs: 8000
    offlineQueueing: true
    debug: true
    accessKeyId: ''
    secretKey: ''
    sessionToken: '')

authenticateClient = ->
  cognitoIdentity = new (AWS.CognitoIdentity)
  AWS.config.credentials.get (err, data) ->
    if !err
      params = IdentityId: AWS.config.credentials.identityId
      cognitoIdentity.getCredentialsForIdentity params, (err, data) ->
        if !err
          # Update our latest AWS credentials; the MQTT client will use these
          # during its next reconnect attempt.
          mqttClient.updateWebSocketCredentials(data.Credentials.AccessKeyId,
              data.Credentials.SecretKey,
              data.Credentials.SessionToken);
        else
          console.log 'error retrieving credentials: ' + err
        return
    else
      console.log 'error retrieving identity:' + err
    return

The socket reconnects fails when trying to reconnect. Attached screenshot of the same. Is there anything that I am missing here?

I came across this issue(https://github.com/aws/aws-iot-device-sdk-js/issues/393) and we are following everything suggested there(Using ats endpoint, using different clientId for each tab, we are not clearing local storage).

Which browser is this happening in? Does this happen in other browsers as well?

@aarthi-mallow did you find any solution for reconnecting. I am also facing the same issue. If the network is back within 10 min it is successfully able to reconnect, after that, it tries to establish the connection even there was a network.
