After internet connection returns mqtt connection doesn't regain

[NikhilGangurde]

Scenario: I am using MQTT for a game firstly user plays for sometimes MQTT works great then I turn off my internet for 5 sec it's off and then the connection turns on again then the connection doesn't establish again only shows reconnecting after a time interval of 35 sec.

For client id, I am using email id(unique)

Code:

func mqttDidDisconnect(session: MQTTSession, error: MQTTSessionError) {
        print("Session Disconnected.")
        if error != .none {
            print("mqttDidDisconnect",error.description)
        }
        reconnectMqttConnection()
    }
    
    func mqttDidAcknowledgePing(from session: MQTTSession) {
        print("Keep-alive ping acknowledged. \(Date())")
        mqttTimer?.invalidate()
        mqttTimer = nil
        mqttTimer = Timer.scheduledTimer(timeInterval: 35.0, target: self, selector: #selector(reconnectMqttConnection), userInfo: nil, repeats: true)
    }
    
    @objc func reconnectMqttConnection() {
        print("********* reconnectMqttConnection ***********")
        mqttSession.disconnect()
        mqttSession = nil
        establishConnection(clientID, matchID: matchID)
    }

Error Log in console After internet connection is turned on again:

********* reconnectMqttConnection *********** 
Trying to connect for client
