        super.viewDidLoad()
        view.addSubview(webView)
        loadCertificates()
        if let identity = identity, let caCertificate = caCertificate {
            server = Server(identity: identity, caCertificates: [caCertificate])
        } else {
            server = Server()
        }
        guard let url = URL(string: "https://localhost:3231/index.html") else {
