updated June 29th, I have updated chromdriver to 75.0.3770.90, but the problem still persists. nothing changes.

+++++++++++++++++++++ June 30th,2019

I have solved this, with "top" command, I saw a progress whose name was kswapd0 consumed too much CPU. It is a progress which is related to swap, so I add this line to /etc/sysctl.conf: vm.swappiness=5 and got more RAM, the service has been running for a day. and no hanging any more. I didn't realize that 1.8GB RAM was not enough for chrome with default configration.

This php error message...

Fatal error: Uncaught Facebook\WebDriver\Exception\WebDriverCurlException: Curl error thrown for http POST to /session with params: {"desiredCapabilities":{"browserName":"chrome","platform":"ANY","chromeOptions":{"w3c":false,"binary":"","args":["--no-sandbox","--headless","--disable-gpu"]}}} Operation timed out after 51627 milliseconds with 0 out of -1 bytes received in /var/www/html/php-selenium/vendor/facebook/webdriver/lib/Remote/HttpCommandExecutor.php:297 Stack trace: #0 /var/www/html/php-selenium/vendor/facebook/webdriver/lib/Remote/RemoteWebDriver.php(144): Facebook\WebDriver\Remote\HttpCommandExecutor->execute(Object(Facebook\WebDriver\Remote\WebDriverCommand)) #1 /var/www/html/php-selenium/s.php(19): Facebook\WebDriver\Remote\RemoteWebDriver::create('http://localhos...', Object(Facebook\WebDriver\Remote\DesiredCapabilities), 50000, 50000) #2 {main} thrown in /var/www/html/php-selenium/vendor/facebook/webdriver/lib/Remote/HttpCommandExecutor.php on line 297

and this selenium error message...

[WARNING]: This version of ChromeDriver has not been tested with Chrome version 75.
03:13:06.892 WARN - Exception thrown
org.openqa.selenium.WebDriverException: java.lang.reflect.InvocationTargetException

...implies that the ChromeDriver was unable to initiate/spawn a new WebBrowser i.e. Chrome Browser session.

Your main issue is the incompatibility between the version of the binaries you are using as follows:

• You are using chromedriver=2.35
• Release Notes of chromedriver=2.35 clearly mentions the following :

Supports Chrome v62-64

• You are using chrome=75.0
• Release Notes of ChromeDriver v75.0 clearly mentions the following :

Supports Chrome version 75

So there is a clear mismatch between ChromeDriver v2.35 and the Chrome Browser v75.0

---

Solution

• Upgrade ChromeDriver to current ChromeDriver v2.75 level.
• Keep Chrome version at Chrome v75 level. (as per ChromeDriver v2.75 release notes)
• Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.

Outro

• Curl error thrown for http POST to /session with params: {“desiredCapabilities”:{“browserName”:“chrome”,“platform”:“ANY” with Selenium and PHPUnit
• Facebook\WebDriver Curl error thrown for http POST to /session with params: {“desiredCapabilities”} error
