The Samsung solution for screen mirroring, which can be called "Screen Mirroring", "Smart View" or "Quick Connect" (depending on what device you use), utilises Miracast. 

It's possible that the device you have AirServer installed on, might not support Miracast. In order to check whether or not the device running AirServer, you can follow the steps in a dedicated support article.

If your receiving device is not compatible with Miracast, it's still possible to mirror using either AirServer Connect or Google Home.
