MQTT client does not connect, disconnects after receiving 0 data from broker

[leonardo-miguel-silva-alb]

Hi, As the titles indicates my client is closing after receiving 0 data from broker. My broker uses a Self Signed Certificate. Next I will indicate my code and logs

`
func selfSignedSSLSetting() { if mqttVesion == "3.1.1" {

        let clientID = "CocoaMQTT-\(animal!)-"
        mqtt = CocoaMQTT(clientID: clientID, host: defaultHost, port: 1883)
        mqtt!.username = "xxx"
        mqtt!.password = "xxx"
        mqtt!.keepAlive = 60
        mqtt!.delegate = self
        mqtt!.allowUntrustCACertificate = true
        mqtt!.logLevel = .debug

    }else if mqttVesion == "5.0" {

        let clientID = "CocoaMQTT5-\(animal!)-"
        mqtt5 = CocoaMQTT5(clientID: clientID, host: defaultHost, port: 1883)

        let connectProperties = MqttConnectProperties()
        connectProperties.topicAliasMaximum = 0
        connectProperties.sessionExpiryInterval = 0
        connectProperties.receiveMaximum = 100
        connectProperties.maximumPacketSize = 500

        mqtt5!.connectProperties = connectProperties
        mqtt5!.logLevel = .debug

        mqtt5!.username = "xxx"
        mqtt5!.password = "xxx"
        mqtt5!.keepAlive = 60
        mqtt5!.delegate = self

        mqtt5!.allowUntrustCACertificate = true

    }

}`
