I have been running Libreelec with TVHEADEND for 2 months now without change anything. Suddenly I dont have any EPG data, using internal XMLTV. When I Re-run the internal EPG grabbers button I get the following in the debug window:
2019-01-12 08:25:36.623 spawn: Executing "/storage/.kodi/addons/service.tvheadend42/bin/tv_grab_file"
