Something is wrong since few releases ago. Solo 4k will be totally unresponsive every now and then. Lock up will happen, display is dead, but audio is working.
SSH is dead, no connection via that way, only living mark is audio which is running on "background". EPG is EIT with nightly refresh and no plugins installed (except s***c*m). Same set up has been a loooooong time, only software updates has been made.
Solo 4k front display is stuck as well when this happen. Issue started maybe since 5.1.21 or so ago.
