Socket io gives a connection error when connecting back from going to background #1455

Open Valeriegard opened 12 months ago

Valeriegard commented 12 months ago

It used to be fine with earlier versions of rep, but now on reconnection, it gives this error. Then it reconnects successfully after around 20s. Don't really know where to look, because I didn't change any connection parameters before updating the socket version. Could someone give a direction on how to fix this?

        socketManager.establishConnection(stationName: UserDefaults.standard.string(forKey: "stationName")!, timeout: 0, password: UserDefaults.standard.string(forKey: "password")!) { //[weak self] in
        }
    }

}

func sceneDidEnterBackground(_ scene: UIScene) {

    if !SharedValues.shared.isStartVC {

    print("DID ENTER BACKGROUND")
        socketManager.closeConnection()
    }
}

`

Socket Manager

` func initializeSocketIO(ip:String, port: String, name: String) {

    manager = SocketManager(socketURL: URL(string: "http://\(ip):\(port)")!, config: [.log(true)])

    socket = manager?.socket(forNamespace: "/")
