Soundcloud api: geotag search not working

Geo search tags do not work. I have an application that works for several months without any changes. This happened recently, and when troubleshooting, I found that the search for geotags, both specific and with wild cards, does not give results.

$(document).ready(function() 
    { SC.initialize({  client_id: 'my id here'}); 
    SC.get("/tracks", {limit: 200, tags: 'geo:lon=-118.*'}, SearchTracks);

    });
var SearchTracks=function Search (tracks){
    for (var key in tracks)  
        {console.log(tracks[key].title+"   "+tracks[key].tag_list);
        }      
};

The same thing happens when I use any other combination of geo: lat and geo: lon. Can any of the Soundcloud comments?
