Debugging link between VBOX and Plex DVR

TL;DR - My working VBOX is picked up by the Plex DVR setup. I can see full EPG and am shown What’s On info. But, no amount of rebooting and reinstalling enables Plex to tune to the live TV feed.

Does the debug log show what’s happening or any suggestions on what I can try?

After many months of failing to get my VBOX working (see https://forums.plex.tv/t/vbox-3442-dose-not-want-to-cooperate for part of my story), I was sent a replacement unit.

The new unit works as advertised and has been stable, streaming live TV to VLC on my Mac and through to my Android Smart TV.

In Plex, the setup process sees the VBOX on the network. The EPG initialises and all channels show up.

However, I am unable to get Plex to show and live TV nor record any programs. The error is always “Playback Error. Could not tune channel. Please check your tuner or antenna.”

VBox is using firmware 2.66 and I’m on the latest Plex media server for my Synology, version 1.19.5.3112.

I enabled logging on Plex to see what would come up. This is the only thing I could find that seemed to relate to the failure:

{

“url”: “https://analytics.plex.tv/collect/event”,
“status”: 200,
“params”: “{“deviceIdentifier”:“dwuptu3n0qop3rahdl9vel1a”,“context”:{“campaign”:{},“device”:{“product”:“Plex Web”,“version”:“4.40.1”,“platform”:“Safari”,“platformVersion”:“13.1”,“device”:“OSX”,“model”:“hosted”,“screenResolution”:“1429x812,1920x1080”,“layout”:“desktop”,“protocol”:“https”},“user”:{“anonymous”:false,“plexpass”:“lifetime”}},“userId”:6640984,“event”:“playback:failure”,“interaction”:true,“properties”:{“serverType”:“owned”,“error”:“tuneFailed”,“identifier”:“003”},“sessionIdentifier”:“5d4db0fc-d26d-460a-8d35-e46c88714022”}”,
“responseLength”: 0,
“time”: “2020-08-23T15:35:25.839Z”
},

Stop the press.

On further digging, it appears Plex is trying to access an invalid IP address that belonged to a different VBox unit that I had to replace. See Plex caching old IP address for TV streamer - how to change for that thread.

I’ve given the VBox a static IP address that matches the one it is looking for and it’s now working as expected.

Out of curiosity, which VBox model did you go with?

I have the VBox 3442 DVB-T/T2 model.

As I write this, it’s been up and running for 26 days straight with no issues at all.
