Unexpected secure connection alert

[lukasz....@uniteam.pl]

I'm getting trouble with unexpected alert exception.

Here is my stacktrace:

org.openqa.selenium.UnhandledAlertException: Modal dialog present: You are about to view pages over a secure connection.

The thing is I can't reproduce exception when I do it manually. I'm confused. My test is pretty simple, I mean it's button.click() and then dialog appear. I have no idea where start debuging and where is a real reason. I authenticate to application over alert().authenticateUsing(new UserAndPassword("login", "password")). I supposed alert().dismiss() will be working but it's not. If I catch WebDriver's IE instance and dismiss dialog by mouse click it works. Button OK redirect me to antoher page of application. Disable option "Warn if changing between secure and not secure mode" doesn't work.

Any ideas?

It's connected with changing protocol. Everytime I start with HTTP protocol and when I click into some button I am redirected to another page which use HTTPS. How deal with that? Are there any solution to this solve my problem? I think the problem is Internet Explorer 11 and settings.
