Unable to click override link on win10 IE 11.3

[wisem2540 3]

I have an IE automation script that runs fine on win7.  But the site I am using frequently displays an "address mismatch" cert error.  The name of that link is "override".  And for some reason it does not click it.  If I bypass it myself, all other fields fill in fine, so it should not be a permissions issue.  Has anyone else seen this behavior?
