TVButler - Unable to find channels

Hello all,
I have a strange issue here. I have installed the latest version of Plex Server and i have a Plex Pass account.
I am using a supported tuner (TVbutler DVBLogic) for DVB/T2 and when i’m using the button in the interface “Scan Channels” the Plex Server doesn’t find any channel.
I tried all the configuration possible for DVB/T2 and no one work :frowning:
I have installed DVBPlayer on my Windows 10 PC and the tuner is able to find 25 channels and it works fine.
I am facing to an issue, i think…
Can you please explain why ? I am using a Raspberry Pi 3 (i think it’s the readynas - ARM version).
Regards,
Matt
