I'm trying to get a Debian VM with Selenium + PHP running again. It was working a few months ago.
I tried running Selenium (in an ssh connection) as the Nginx user and as root. Both produce the same error
java -jar ./selenium-server-4.1.1.jar standalone
Starting ChromeDriver 97.0.4692.71 (adefa7837d02a07a604c1e6eff0b3a09422ab88d-refs/branch-heads/4692@{#1247}) on port 53084
Only local connections are allowed.
Please see https://chromedriver.chromium.org/security-considerations for suggestions on keeping ChromeDriver safe.
ChromeDriver was started successfully.

My code (which was working) is as follows
require __DIR__ . '/../vendor/autoload.php';
putenv('WEBDRIVER_CHROME_DRIVER=/var/www/chromedriver');
use Facebook\WebDriver\Remote\RemoteWebDriver;
use Facebook\WebDriver\Remote\DesiredCapabilities;
use Facebook\WebDriver\WebDriverBy;
$serverUrl = 'http://localhost:4444/';
$driver = RemoteWebDriver::create($serverUrl, DesiredCapabilities::chrome());
$driver->get('https://en.wikipedia.org/wiki/Selenium_(software)');
// Find search element by its id, write 'PHP' inside and submit
$driver->findElement(WebDriverBy::name('search')) // find search input element
->sendKeys('PHP') // fill the search box
->submit(); // submit the whole form
// Find element of 'History' item in menu by its css selector
$historyButton = $driver->findElement(
WebDriverBy::cssSelector('#ca-history a')
);
// Read text of the element and print it to output
echo 'About to click to a button with text: ' . $historyButton->getText();
// Click the element to navigate to revision history page
$historyButton->click();
// Make sure to always call quit() at the end to terminate the browser session
$driver->quit();
I assume it's something to do with how the services are running. I tried making Chromedriver run in the background as well. I also tried connecting via
$serverUrl = 'http://localhost:4444/wd/hub/';
But that did not help.
Edit
I tried updating Chrome to 103, updating the corresponding Chromedriver and running Selenium 4.3.0 and that changed nothing at all. I tried all different combinations of running Selenium from different users. I also moved Chromedriver into /usr/bin and tried assigning it different permissions.
