On 20-21 June Google changed policy, so starting with Chrome 50, Chrome no longer supports obtaining the user’s location using the HTML5 Geolocation API from pages delivered by non-secure connections.
This means that the page that’s using the Geolocation API call must be served from a secure context such as HTTPS.
See this article for details: https://developers.google.com/web/updates/2016/04/geolocation-on-secure-contexts-only
