You can see some discussion on similar topic here.

Ther are couple different solutions, but what worked for me, was replacing all requests for css and js, to use http rather than default https:

So for example, this:

<link rel="stylesheet" href="http://localhost/css/site.css">

instead of this:

<link rel="stylesheet" href="~/css/site.css">
