Kodi Freez after some minutes

Hi all,
I have some problem with my TvHeadend server (Build: 4.1-1708~g4c75447~trusty)
I succesfully installed the HTPS plugin for kodi but When I watch a channel that is blocked after a few minutes, This happens with any stream profile.

How I can fix this problem?
I use Kodi 16.0 on Windows and Android device (Android TV).

Thanks to all
