Authentication when executing in Kobiton not working

When executing tests on a Kobiton mobile devices the authentication does not work.

I tried below methds:

WebUI.navigateToUrl('https://admin:password@ux-int.bop....', FailureHandling.OPTIONAL)
WebUI.openBrowser('')
autoit_prj = 'D:\\Project\\katalonh5-2.1\\auth.exe'
Runtime.getRuntime().exec(autoit_prj)
Thread.sleep(3000);
WebUI.navigateToUrl('https://ux-int.bop....')
WebUI.authenticate('http://ux-int.bop....', 'admin', 'password', 12)

I used the AutoIt like the example in the Katalon docs shows.
But none of these methods does anything or throws an error.

Any ideas what i’m doing wrong?

Regards.
