testing: selenium chrome driver select certificate popup confirmation not working

mardi 27 mars 2018

I am automating tests using selenium chromewebdriver 3.7. Whenever I lauch the site, I get a certificate selection popup like the one below

However I am not able to click on the OK button. These are the options I have tried

 //I have tried getWindowHandle like this  
 String  handle= driver.getWindowHandle();
        this.driver.switchTo().window(handle);

//I have alos tried switching and accept
 driver.switchTo().alert().accept();

//I have also tried to force the enter key like this
 robot.keyPress(KeyEvent.VK_ENTER);
 robot.keyRelease(KeyEvent.VK_ENTER);

 // I also tried this way
 Scanner keyboard = new Scanner(System.in);
 keyboard.nextLine();

All my trials have failed. How can I click on OK on this popup window? This is the closest solution I found which is not working Link here
