Dotnetbrowser没有读我的代理？

Question

我已按照此处的文档https://dotnetbrowser.support.teamdev.com/support/solutions/articles/9000110853-configuring-proxy使用TeamDev使用DotNetBrowser配置代理，并且根本没有检测到我的代理。

                string mainPage = "https://www.example.com";
                String proxyRules = "http=127.0.0.1:8085;https=127.0.0.1:8085;ftp=127.0.0.1:8085;socks=127.0.0.1:8085";
                String exceptions = "<local>";
                String dataDir = Path.GetFullPath("chromium-data");
                BrowserContextParams contextParams = new BrowserContextParams(dataDir);
                contextParams.ProxyConfig = new CustomProxyConfig(proxyRules, exceptions);

                using (Browser browser = BrowserFactory.Create(new BrowserContext(contextParams)))
                {
                    ManualResetEvent waitEvent = new ManualResetEvent(false);
                    browser.FinishLoadingFrameEvent += delegate (object sender, FinishLoadingEventArgs e)
                    {
                        // Wait until main document of the web page is loaded completely.
                        if (e.IsMainFrame)
                        {
                            ...
                            waitEvent.Set();
                        }
                    };
                    browser.LoadURL(mainPage);
                    waitEvent.WaitOne();
                    return true;
                }
