Why i am getting this error? Here error detail:

Setting error display: 'Invalid Unity Web File (Decompression Failure).', details: '', link: 0

  string pageURL = "";
 System.Uri uri;
 string[] parts;
 
 if(GUI.Button(new Rect(375,220,210,160)," ")){
 uri = new System.Uri(Application.absoluteURL);
 parts = uri.Host.Split('.');
 System.Array.Reverse(parts);
 for(var i = 0; i < parts.Length; i++)
 {
 pageURL = parts[1];
 }
 Application.OpenURL("http://www.mywebsite.com/?utm_source=mygame&utm_medium=" + pageURL + "&utm_campaign=logo");
 }
