browsermob-proxy: Embedded mode with selenium doesn't load website

When using embedded mode in a selenium test, websites will timeout and not load. I have tried on google, npr.org, yahoo.com, etc. I’ve tried a couple things to see if it makes a difference but no luck so far: setting setUseECC to true, setTrustAllServers to true. I’ve tried on 2 different machines and same results. Is there something I’m missing?

Java v8 selenium v3.3.1 bmp v2.1.4

Here is my test case:

// Create bmp proxy
		BrowserMobProxyServer proxy = new BrowserMobProxyServer();
		// proxy.start(0);
		try {
			proxy.start(9091, InetAddress.getLocalHost());
		} catch (UnknownHostException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		proxy.setHarCaptureTypes(CaptureType.getAllContentCaptureTypes());
		proxy.enableHarCaptureTypes(CaptureType.REQUEST_CONTENT, CaptureType.RESPONSE_CONTENT);
		proxy.setUseEcc(true);

		// Pass the proxy into desired capabilities
		Proxy seleniumProxy = ClientUtil.createSeleniumProxy(proxy);
		DesiredCapabilities caps = new DesiredCapabilities();
		caps = DesiredCapabilities.chrome();
		caps.setCapability(CapabilityType.PROXY, seleniumProxy);

		// Turning off pop-up blocking
		ChromeOptions options = new ChromeOptions();
		options.addArguments("test-type");
		options.addArguments("disable-popup-blocking");
		caps.setCapability(ChromeOptions.CAPABILITY, options);

		// Create the browser session
		File file = new File(this.getClass().getResource(Constants.DRIVERS_PATH_LOCAL + "ChromeDriver.exe").getPath());
		System.setProperty("webdriver.chrome.driver", file.getAbsolutePath());
		WebDriver driver = new ChromeDriver(caps);

		// Create the har file

		proxy.newHar("SalesforceAddCandidate");

		// load website stuff
		
		driver.get("http://www.npr.org/");

		Har har = proxy.getHar();

		File harFile = new File("C:\\temp\\SalesforceAddCandidate");
		try {
			har.writeTo(harFile);
		} catch (IOException ex) {
			System.out.println(ex.toString());

		}
		proxy.stop();
