Laravel Dusk: FacebookWebDriverExceptionUnknownErrorException: unknown error: net::ERR_CONNECTION_REFUSED

Running php artisan dusk get the error:

FacebookWebDriverExceptionUnknownErrorException: unknown error: net::ERR_CONNECTION_REFUSED
  (Session info: headless chrome=85.0.4183.83)

Versions:

  • OS: Windows 10 v1903 build 18362.1016
  • Chrome: 85.0.4183.83
  • Laravel: v6.18.37
  • Dusk: v5.11.0
  • Phpunit: v8.5.8

Tried:

  • Disable firewall
  • Set test website to use localhost (was myapp.local)
  • Can access all pages using Chrome browser
  • Check that vendor/laravel/dusk/bin/chromedriver-win.exe is executable (-rwxr-xr-x)
  • php artisan route:clear
  • php artisan cache:clear
  • php artisan config:clear
  • composer dump-autoload
  • google “FacebookWebDriverExceptionUnknownErrorException: unknown error: net::ERR_CONNECTION_REFUSED”

The server localhost:9515 appears to be running while tests executing as I get the following response in Chrome when trying it:

{
    value: {
        error: "unknown command",
        message: "unknown command: unknown command: ",
        stacktrace: "Backtrace: Ordinal0 [0x0037D383+3134339] Ordinal0 [0x0026A171+2007409] Ordinal0 [0x0010AEE8+569064] Ordinal0 [0x000AD12C+184620] Ordinal0 [0x000ACF0A+184074] Ordinal0 [0x00081FD7+8151] Ordinal0 [0x00082496+9366] Ordinal0 [0x00082B40+11072] Ordinal0 [0x00280CD9+2100441] GetHandleVerifier [0x004EB75A+1396954] GetHandleVerifier [0x004EB3D9+1396057] GetHandleVerifier [0x004F7126+1444518] GetHandleVerifier [0x004EBCE8+1398376] Ordinal0 [0x00277F51+2064209] Ordinal0 [0x00081D35+7477] Ordinal0 [0x00081991+6545] GetHandleVerifier [0x006BF31C+3312796] BaseThreadInitThunk [0x76986359+25] RtlGetAppContainerNamedObjectPath [0x771D7C24+228] RtlGetAppContainerNamedObjectPath [0x771D7BF4+180] (No symbol) [0x00000000] ",
    }
}

DuskTestCase driver:

/**
 * Create the RemoteWebDriver instance.
 *
 * @return FacebookWebDriverRemoteRemoteWebDriver
 */
protected function driver()
{
    $options = (new ChromeOptions)->addArguments([
        '--disable-gpu',
        '--headless',
        '--window-size=1920,1080',
    ]);

    return RemoteWebDriver::create(
        'http://localhost:9515', DesiredCapabilities::chrome()->setCapability(
            ChromeOptions::CAPABILITY, $options
        )
    );
}

Does anyone have any clues on what else to try? Or does anyone else know a resolution?

Answer

I faced the same issue and for me what worked was setting the APP_URL parameter in the .env file as:

APP_URL=http://127.0.0.1:8000

As that was the same port on which my php artisan serve would also serve the website i.e.

Laravel development server started: http://127.0.0.1:8000
