проблема с запуском RemoteWebDriver с прокси

Помогите, пожалуйста, разобраться с ошибкой. При запуске, все прокси инициализируются, а браузер так и не запускается. код:

public static WebDriver initFireFoxWithProxyDocker() throws MalformedURLException {
        DesiredCapabilities capability = DesiredCapabilities.firefox();

        Proxy proxy = new Proxy();
        String comProxy = "us.proxy.*******.com:3128";

        proxy.setProxyType(Proxy.ProxyType.MANUAL);
        proxy.setHttpProxy(comProxy);
        proxy.setFtpProxy(comProxy);
        proxy.setSocksProxy(comProxy);
        proxy.setSslProxy(comProxy);

        capability.setCapability(CapabilityType.PROXY, proxy);

        WebDriver driver = new RemoteWebDriver(new URL(getProps().getRemoteWebDriverUrlWithDocker()), capability);

        return driver;

ошибка:

Скорее всего, надо порт отдельно указывать. У вас сама шибка и выдаёт - ожидается интеджер.
GitHub - mozilla/geckodriver: WebDriver for Firefox - раздел WebDriver capabilities - proxy object для каждого Proxy надо указывать порт.

не нашла функцию для задания порта отдельно и в классе Proxy есть только такие параметры
public class Proxy {
private Proxy.ProxyType proxyType;
private boolean autodetect;
private String ftpProxy;
private String httpProxy;
private String noProxy;
private String sslProxy;
private String socksProxy;
private String socksUsername;
private String socksPassword;
private String proxyAutoconfigUrl;

Да, поспешил я, посмотрел - да, вы правильно задаёте прокси, моя подсказка неверна.
А версия геккодрайвера свежая?

Это удаленный вебдрайвер, там последняя версия.
