One suggestion I would make, after all the other mentioned are not working, use Start Application activity to open IE instead of Open browser.
Use type into (address bar), instead of navigate to. Your rest of the sequence would work (selectors and all) in the Start Application Activity Sequence.
Hi,
I have the same kind of issue but slightly different. I am getting the same error for almost all the browsers.
I am able to open the browser and access the URL of the site. When the Login pop up opens up I am getting this error. If I manually give the credentials then other processes are running smoothly without any issue. please help me as I am struck with this issue for a quite long time.
