I have a script which I can't get working. I keep getting the error 'Geocoder failed' but I am not sure why. It is supposed to get the long/lat and then reverse geocode it to show the street address in an alert box. I have tried ensuring that the browser is letting it share the location. I have also tried accessing via HTTPS as I read that this was needed now but it still doesn't work. If anyone can help me to get this working I would be most grateful! Thanks in advance.
