Chrome browser fails to launch

[Hermes]

Hi, sometimes when I run my script in GUI (SciTe Editor) or as an executable file, the chrome driver launches but the chrome browser does not but when I re-run the script again - chrome driver launches and so does the browser. Here is the error that I'm getting:

__WD_Post: StatusCode=0; ResponseText=WinHTTP request timed out before Webdriver...

__WD_Post ==> Send / Recv error: WinHTTP request timed out before Webdriver

_WD_CreateSession: WinHTTP request timed out before Webdriver

_WD_CreateSession ==> Webdriver Exception: HTTP status = 0

Just wondering if there's a way to re-launch both the driver and browser without having to rerun the script/executable.

What capabilities are you using?

Thanks for responding, here's the function i have for capabilities:

Func SetupChrome()

    _WD_Option('Driver', 'chromedriver.exe')

    _WD_Option('Port', 9515)

    _WD_Option('DriverParams', '--log-path="' & @ScriptDir & '\chrome.log"')

    $sDesiredCapabilities = '{"capabilities": {"alwaysMatch": {"goog:chromeOptions": {"w3c": true, "args":["start-maximized","disable-infobars"]}}}}'

EndFunc   ;==>SetupChrome

It's not a capabilities issue, it launches sometimes and other times it doesn't launch at all.

@Danp2 Hi, is this some kind of a glitch in Auto It v 3.3.14.5, and  SciTe Editor (32-bit Version 4.2.0)? Or is there a way to solve it?

From a quick read (so I might be wrong), @Danp2 mentions here to try:

• Update to the latest WinHTTP here
• Change the default WinHTTP Timeouts
• Set the following in your capabilities and use _WD_LoadWait 

  "pageLoadStrategy":"none"

If I remember rightly, I had the same problem and set the timeouts in the capabilities which fixed the issue.

"timeouts": {"implicit": 0, "pageLoad": 60000, "script": 30000}

Try:

Func SetupChrome()

    _WD_Option('Driver', 'chromedriver.exe')

    _WD_Option('Port', 9515)

    _WD_Option('DriverParams', '--log-path="' & @ScriptDir & '\chrome.log"')

    $sDesiredCapabilities = '{"capabilities": {"alwaysMatch": {"goog:chromeOptions": {"w3c": true, "args":["start-maximized","disable-infobars"], "timeouts": {"implicit": 0, "pageLoad": 60000, "script": 30000}}}}}'

EndFunc   ;==>SetupChrome

I wasn't able to test the above code.

@HermesIf might help if you showed the complete Scite output when Chrome fails to launch. Have you checked Chrome.log for any meaningful details on why it failed to launch the browser?
