Connection always fails with unspecified "Error" #1333

Closed michaellie99 closed 3 years ago

michaellie99 commented 3 years ago

The socket connection seems to always fail, the connection seems to be found but fails to connect which led me to believe that something else is wrong in my code. Here is the class that I made to handle the socket.io request:

class WebSocketService{

var manager = SocketManager(socketURL: URL(string: "http://192.168.0.140:3000")!, config: [.log(true), .reconnects(false)])

var socket:SocketIOClient!

init(){
    socket = manager.defaultSocket
    setup()
}
func setup(){
    socket.on(clientEvent: .connect){ (data,ack) in
        print("Socket Connected")
    }
    socket.on(clientEvent: .disconnect){ (data,ack) in
        print("Socket Disconnect")
    }
    socket.on(clientEvent: .reconnect){ (data,ack) in
        print("Event: Trying to reconnect \(data)")
    }
    socket.on(clientEvent: .ping){ (data,ack) in
        print("Event: Socket pinged\(data)")
    }
    socket.on(clientEvent: .error){ (data,ack) in
        print("Event: Error, ERROR Occured \(data)")
    }
    socket.on(clientEvent: .reconnectAttempt){ (data,ack) in
        print("Event: Reconnection Attempt Occured \(data)")
    }
    socket.on(clientEvent: .pong){ (data,ack) in
        print("Event: Socket ponged\(data)")
    }

}
func stop(){
    socket.disconnect()
}
func start(){
    socket.connect()
}
func sendMsg(){
    socket.emit("Server", "Hello")
}
}

Here are the logs

Any help would be appreciated, thanks in advance.

What's the client version / server version? If you're trying to connect to a socket.io 2.0 server with 16 client, you'll need to pass the .version(.two) option.

Im using both the latest available socketio (3.0) and client(?) I dont know how to check the client version but I'm using socketio v15.2.0 for the pod installation Where do I pass this version option? It doesn't show up in the configs

@michaellie99 for socket.io 3, you need to use v16

michaellie99 commented 3 years ago

@nuclearace thanks, Installing v16 works, I was kinda confused because the latest release version was 15.2.0, to the people having the same issue as me, the fix is changing the version of socket.io installed in the Podfile (or carthage, etc if you dont use cocoapods) to '~> 16.0.1'.
