DVR "There was a problem discovering devices"

My plex crashed for some reason, but got it up and running again except the DVR part

not it can’t find the tuner anymore and i get the “There was a problem discovering devices”

Worked fine before the crash…

Tvtuner is Hauppauge WinTV-dualHD

What to try?

If you provide the server logs covering time of the crash then we can see what was happening before the crash

Have you tried deleting the DVR and setting it up afresh?
