Could not tune channel. Please check your tuner or antenna

Hi,

I receive the following error when trying to play/channel via Plex using in this case Threadfin. About a year ago I had it working but that was via a dvb-t dongle not using something such as Threadfin.

Server Version#: 1.42.1.10060
Player Version#:
Tuner Make/Model: Using Threadfin 1.2 (35)
Guide/Lineup name:
Using XMLTV?: Yes
Channel number/Name: 15

Tried going back to version 1.41.0.8994-f2c27da23 but still the original problem persists. Also, installed Plex player same message appears there too.

Plex is only using secure connections these days, so your docker should use host mode for networking. Get this working correctly and you might solve your other issue.

Threadfin support will have to happen elsewhere.

Yeah, I change the Plex container type“–net“ to “host“ but same problem but thanks for the input.
