use

 ArrayAdapter<String> arrayAdapter =new ArrayAdapter<String>(MainActivity.this,android.R.layout.simple_list_item_1,serverarray);

this in your current context is MainActivity.FindServer which is not a valid Context object i believe.

The constructor you are trying to invoke is of signature:

ArrayAdapter(Context context, int resource, List<T> objects)

The 2nd and third 3rd arguments seem okay, so probably this as a first argument is not of type Context.

You need to pass a reference to the context of MainActivity in your MainActivity.FindServer class, and then pass that as your first argument.
