Xcode Swift项目连接WebSocket遇NSURLErrorDomain Code=-1005错误求助

我正在开发iOS项目，需要连接WebSocket，以下是实现连接的代码：

class WebSocketTaskConnection: NSObject, WebSocketConnection, URLSessionWebSocketDelegate {
    var delegate: WebSocketConnectionDelegate?
    var webSocketTask: URLSessionWebSocketTask!
    var urlSession: URLSession!
    let delegateQueue = OperationQueue()
    
    init(token: String) {
        super.init()
        
        let tokenFilter = token.substring(from: 7)
        
        
        var components = URLComponents(string: WebSocketUrls.baseSocketUrl)!
        components.queryItems = [URLQueryItem(name: "token", value: tokenFilter),
                                 URLQueryItem(name: "os_type", value: "ios")]
        
        print("WebSocketTaskConnection URL", components.url ?? "---")
        
        urlSession = URLSession(configuration: .default, delegate: self, delegateQueue: delegateQueue)
        webSocketTask = urlSession.webSocketTask(with: components.url!)
    }
    
    func urlSession(_ session: URLSession, webSocketTask: URLSessionWebSocketTask, didOpenWithProtocol protocol: String?) {
        self.delegate?.onConnected(connection: self)
    }
    
    func urlSession(_ session: URLSession, webSocketTask: URLSessionWebSocketTask, didCloseWith closeCode: URLSessionWebSocketTask.CloseCode, reason: Data?) {
        self.delegate?.onDisconnected(connection: self, error: nil)
    }
    
    func connect() {
        webSocketTask.resume()
        
        listen()
    }
    
    func disconnect() {
        webSocketTask.cancel(with: .goingAway, reason: nil)
    }
    
    func listen()  {
        webSocketTask.receive { result in
            switch result {
            case .failure(let error):
                self.delegate?.onError(connection: self, error: error)
            case .success(let message):
                switch message {
                case .string(let text):
                    self.delegate?.onMessage(connection: self, text: text)
                case .data(let data):
                    self.delegate?.onMessage(connection: self, data: data)
                @unknown default:
                    fatalError()
                }
                
                self.listen()
            }
        }
    }
    
    func send(text: String) {
        webSocketTask.send(URLSessionWebSocketTask.Message.string(text)) { error in
            if let error = error {
                self.delegate?.onError(connection: self, error: error)
            }
        }
    }
    
    func send(data: Data) {
        webSocketTask.send(URLSessionWebSocketTask.Message.data(data)) { error in
            if let error = error {
                self.delegate?.onError(connection: self, error: error)
            }
        }
    }
}

尝试连接时出现如下错误：

已尝试的操作：

• 重置并重启模拟器
• 重启Xcode
• 在iPhone真机运行并重装应用

恳请大家提供解决思路。
