ssl - Xamarin Android HttpClient Error when use from a Class -

i have following code errors out when going site has ssl. (error: securechannelfailure (the authentication or decryption has failed.) ssl cert valid. when httpclient code called directly there not issue. wrong code?

 uri uri =new uri("https://jsonplaceholder.typicode.com/posts/1");   using (httpclient httpclient = new httpclientclass())    {        var tt = await httpclient.getasync(uri);        string tx = await tt.content.readasstringasync();        log.info(tag, tx);     }      public class httpclientclass : httpclient   {      private httpclient _httpclient = null;      private httpclienthandler messagehandler = new xamarin.android.net.androidclienthandler();       public  httpclientclass()      {        _httpclient = new httpclient(messagehandler);       }    } 

code no problem

uri uri =new uri("https://jsonplaceholder.typicode.com/posts/1");   using (httpclient httpclient = new httpclient())    {        var tt = await httpclient.getasync(uri);        string tx = await tt.content.readasstringasync();        log.info(tag, tx);     }
