SessionNotCreatedException when trying to connect to headless chrome on Ubuntu

[Nikki Pris]

I'm running chrome (chromium) on a Ubuntu server with the following command:

./chrome --headless --disable-gpu --remote-debugging-address=192.168.0.22 --remote-debugging-port=9222

I can connect to it from my local machine via the web browser and receive the following text in my web browser:

Inspectable WebContents
about:blank

When I attempt to connect to it using Selenium (using selenium-chrome-driver 3.3.1), with the following code:

WebDriver driver = new RemoteWebDriver(new URL("http://192.168.0.22:9222"), DesiredCapabilities.chrome());
driver.get("http://www.google.com");

I get the following SessionNotCreatedException:

If I purposely put in an incorrect IP address I get a UnreachableBrowserException, so I know it's reaching the server. What am I do wrong? Thanks!
