The only browser I see as having a problem is Firefox Here's that screen shot.

Ad. Chrome - please click green padlock icon then Connection Tab, make screenshot and post on forum
Ad. Edge - browser does not show the connection details
Ad. IE - why browser dispalys blue question mark icon [?] and not green like e.g. mozilla.org, paypal.com, mbank.pl etc.
