Невозможно запустить тест автоматизации (с использованием selenium, C#) на browserstack, за корпоративным прокси-сервером

---

Я получаю следующую ошибку при создании экземпляра RemoteWebDriver

driver = new RemoteWebDriver(new Uri("http://hub-cloud.browserstack.com/wd/hub/"), capability);

Unable to connect to the remote server ---> System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond XXX.XXX.XXX.XXX:Port

Что я уже пробовал:

var browserStackLocal = new Local();
            var localArgs = new List<KeyValuePair<string, string>>
            {
                new KeyValuePair<string, string>("key", "XXXXXXXXXXXXXXXXXXXXX"),
                new KeyValuePair<string, string>("force", "true"), 
                new KeyValuePair<string, string>("binarypath", "/temp"), 
                new KeyValuePair<string, string>("logfile", "/temp/logs.txt"),
                new KeyValuePair<string, string>("v", "true"),
                new KeyValuePair<string, string>("proxyHost", "HostName"),
                new KeyValuePair<string, string>("proxyPort", "PortNumber"),
                new KeyValuePair<string, string>("proxyUser", "Username"),
                new KeyValuePair<string, string>("proxyPass", "Password")
            };

              browserStackLocal.start(localArgs);

                DesiredCapabilities capability = new DesiredCapabilities();
                capability.SetCapability("browser", "Chrome");
                capability.SetCapability("browser_version", "62.0");
                capability.SetCapability("os", "Windows");
                capability.SetCapability("os_version", "7");
                capability.SetCapability("resolution", "1024x768");
                capability.SetCapability("browserstack.local", "true");
                capability.SetCapability("browserstack.debug", "true");
                capability.SetCapability("browserstack.user", "UserXXXXXX");
                capability.SetCapability("browserstack.key", "KeyXXXXXX");

                driver = new RemoteWebDriver(new Uri("http://hub-cloud.browserstack.com/wd/hub/"), capability);
                driver.Navigate().GoToUrl("http://google.co.uk");

Option 1) I am able to establish a connection using the following code:
browserStackLocal.start(localArgs);

But, still getting “Unable to connect to the remote server ---> System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 185.44.131.194:80”, in the following code:

driver = new RemoteWebDriver(new Uri("http://hub-cloud.browserstack.com/wd/hub/"), capability);


Option 2) Also tried the following command 
BrowserStackLocal.exe --key XXXXXX --proxy-host Host --proxy-port Port --proxy-user Username --proxy-pass Password --force-local --force-proxy

And adding the following code
capability.SetCapability("browserstack.local", "true");

Если кто-то столкнулся с этой проблемой, пожалуйста, поделитесь своим опытом и решением.
