I inherited a web app written in c#/MVC (.NET 4.0)
The only page that is giving trouble is the one that accesses Google Maps. It is consistently giving me the dreaded forbidden 403 error. The identical issue is occurring on I should mention that this had been working for many months without issue, and just all of a sudden started occurring. It is conceivable that a Windows Update may have initiated this problem. Are there any IIS settings or User Permissions I could modify that would prevent this issue from occuring. I tried temporarily given Full Access to the Everyone user, but this made no difference. Here is all the details I can provide:

In my Controller file, the only method that uses Google Maps is the following:
private Dictionary<string, double> GetPatientLatLong(string address)
{
Dictionary<string, double> latlong = new Dictionary<string, double>();
var Patientadd = address;
var locationService = new GoogleLocationService();
var point = locationService.GetLatLongFromAddress(Patientadd);
if (point != null)
{
var latitude = point.Latitude;
var longitude = point.Longitude;
latlong.Add("latitude", latitude);
latlong.Add("longitude", longitude);
}
else
{
latlong.Add("latitude", 0);
latlong.Add("longitude", 0);
}
return latlong;
}
In the .cshtml file, this is written at the top
<script src="https://maps.googleapis.com/maps/api/js?key={thekey}"></script>
followed by:
<script>
google.maps.event.addDomListener(window, 'load', initialize);
function initialize() {
var markerArray = [];
var infoWindow = new google.maps.InfoWindow();
var miles = @Model.TherapRadius;

var myLatlng2 = new google.maps.LatLng(@Model.patientLat, @Model.patientLong);
var mapOptions = {
center: new google.maps.LatLng(29.760193,-95.369390),
zoom:10,
}
var map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
var geocoder = new google.maps.Geocoder();
var marker1;
for (var i = 0; i < myModel.coveringAreas.length; i++) {

color:"Blue",

});
marker2.setMap(map);

}
}
function addMarkerDetails(i)
