Unable to load tv stream after setting up threadfin

I successfully set up threadfin and my server can see the “tuner”.

I am using the following URLs for my iptv:

Playlist: http://tvpass.org/playlist/m3u
EPG: Storage Wars

Plex can see the epg and channels, but when I try to select a channel, I get the error “unable to tune or unable to play”.

I did some digging around and I did test the playlist to see if it plays in VLC and it does. So not sure what I’m doing wrong. Any help would be hugely appreciated. TIA!
