Selenium connection refused within docker

Question

I'm attempting to use Laravel Dusk alongside Selenium to run browser tests. I have my platform and selenium running within docker that are composed together in the same dockerfile.

Each time I try to run php artisan dusk I get the error messsage:

Facebook\WebDriver\Exception\UnknownErrorException: unknown error: net::ERR_CONNECTION_REFUSED
(Session info: chrome=113.0.5672.63)

I have tried switching APP URL (localhost runs on port 8990) in every combination alongside other flags within DuskTestCase. Selenium grid opens correctly at http://127.0.0.1:4444/

docker-compose.yml

  chrome:
    image: selenium/node-chrome:4.9.1-20230508

    ports:
      - "4442:4442"
      - "4443:4443"
      - "4444:4444"

DuskTestCase.php

$options = (new ChromeOptions)->addArguments(collect([
    $this->shouldStartMaximized() ? '--start-maximized' : '--window-size=1920,1080',
])->unless($this->hasHeadlessDisabled(), function (Collection $items) {
    return $items->merge([
        '--disable-gpu',
        '--headless=new',
        '--whitelisted-ips=""',
        '--disable-dev-shm-usage'
    ]);
})->all());

return RemoteWebDriver::create(
    'http://selenium-hub:4444/wd/hub', DesiredCapabilities::chrome()->setCapability(
    ChromeOptions::CAPABILITY, $options
)
);

I'm running out of things to try at this point. For reference, my system uses Ubuntu.
