Dusk Testing 在服務器上出現錯誤 Curl error thrown for http POST to /session with params

各位好，想请教一下我在 Plesk Server 尝试执行以下指令：

php artisan dusk

会出现如下错误：

1) Tests\Browser\ExampleTest::testBasicExample
Facebook\WebDriver\Exception\WebDriverCurlException: Curl error thrown for http POST to /session with params: {"desiredCapabilities":{"browserName":"chrome","platform":"ANY","chromeOptions":{"binary" :".\/vendor\/laravel\/dusk\/bin\/chromedriver-linux","args":["--disable-gpu","--headless","--no-sandbox"," --verbose","--window-size=1024,768"]}}}

我怀疑过是否无法执行 Chrome Driver ，因此用了以下指令检测：

./vendor/laravel/dusk/bin/chromedriver-linux

回传如下：

Starting ChromeDriver 2.43.600233 (523efee95e3d68b8719b3a1c83051aa63aa6b10d) on port 9515
Only local connections are allowed.

表示 ChromeDriver 可以正常开启的。
且程式码在本机电脑也可以完成检测，仅在 Plesk Server 时执行 dusk 指令才会出现错误，请问各位大神我该继续做什么检测或是该修改哪些内容呢？谢谢！

伺服器规格如下：
CentOS 7.5
PHP 7.1
DB SQLite3
Laravel Version 5.7
ChromeDriver Version 69
