So, I’m getting the dreaded screen above. I’ve tried 3 or 4 different browsers (Edge, Firefox and Chrome for sure), 3 different computers (the server itself, my main desktop, and a laptop), the plex desktop app, shutting down PMS and starting it back up, restarting my plex server, turning off all firewalls, waiting overnight, plugging my tuner into different USB ports, etc. Seems that nothing I do will let me scan channels. I was able to do it once over the past weekend, I can’t remember what browser or computer allowed me to do it, but I found my antenna’s cable was broken, so it didn’t find any channels. I purchased a new antenna and now I’m trying to get the channels to scan and getting nothing. The button just does not work.

I just updated PMS to the latest version tonight too, I was hoping there would be a fix added, but nope.

I’m using the Hauppage WinTV-dualHD and I know it’s working because the app that comes with it (WinTV 8) is picking up channels and letting me watch them from my PMS server.

I’m using this version of Plex on a Win10 Pro “server” build 20H2 with the only caveat being that it’s a virtual machine in my ESXi 6.5u3 cluster.

That shouldn’t matter though, since I know the USB tuner is being passed properly to the VM, since I can watch shows from the server itself.

Anyone have any pointers on getting this working, or clearing up some cache or anything? Just trying to get this to work.

Thanks!

Also, I have removed the WinTV 8 software just to make sure it’s not interfering with the Plex server either.

I have also just tried doing a scan from the online app, with the same results: https://app.plex.tv/desktop/

Look, I know it’s probably pretty low priority by the plex team, and not a highly utilized feature but I’m hoping someone can advise of something I can try to get this to work. I do have Supported hardware and a plex pass, just hoping someone can help me troubleshoot further

Pretty sure this broke again in the server release sent out yesterday.

TBH I dont see this being fixed again reliably soon based on how plex’s development has been the past few years.

I had to roll back to the previous server release for other channel matching related issues that re-appeared…

Unfortunately, that was a fear of mine. I mean it didn’t work in the release prior to yesterday’s build either. Thanks for the feedback though, I appreciate your time!

5

Unfortunately, going back to Version 1.25.5.5492 did not seem to help. Tried desktop app, desktop in chrome and server with Edge and none of them let me click on the scan channels button

6

Anyone from the Plex team that could help? Can I find and upload some logs to help diagnose and troubleshoot?

7

Finding this in my console, don’t know if it helps any:

Then it’s followed by this:

That is indicative of the issue of the Plex Tuner Service crashing and then the tcp port is not being released

I have an alpha release of 1.25.8 being tried by a number of users - I will add you to the private message thread

Much appreciated! I can say that I did a fresh install of PMS on my personal computer and plugged the tuner in, installed the driver and Plex was able to scan for channels just fine and was able to tune. So, something on my server is messed up but I don’t know what.

10

unfortunately, the version that was posted : Version 1.25.8.5621 doesn’t seem to make any difference for me. My console still shows the same error when I attempt to click on the Scan Channels button:

On first launch of the new version - you may get the error because the port was not released. May need a system reboot

Also - the error may get logged if the request is made before the PTS process got establish.

Restart again and get me full server logs zip and I will see if we still have an issue

12

Sorry, didn’t see this reply. Thanks I’ll reboot, try again, and post logs again if it still doesn’t help. Much appreciated!

13

Reboot didn’t appear to have helped, including latest logs

You have a different issue - some permissions problem on your windows setup

Have you made any changes to user permissions ? filesystem permissions ? install directory ? system policies

Plex Media Server is unable to spawn off processes

Is this windows 10 ?

15

Hmm, that’s strange. No, I don’t think I did anything out of the ordinary permissions-wise. Yes, I’m running Windows 10 Pro, build 20H2. The PMS process runs as local Administrator and it was installed in the standard install directory.

I just tried closing and launching “As Administrator” and that didn’t seem to help either. I don’t have any third-party A/V running, just the built-in MS Defender and I have the firewall off right now for troubleshooting purposes.

17

Going to do the 21H2 update and see if it makes any difference, if not, I can try uninstalling and re-installing PMS. Thankfully this is a virtual machine, so I can take a snapshot and restore it if breaks anything.

Thanks for your help so far!

Updating to latest windows build and re-installing Plex didn’t work. Might have to start from scratch I guess. Not sure what the problem is. There’s pretty much nothing on this computer besides Plex server, Ombi and Tautulli. Nothing special about Windows either.

19

I am back on Friday - will give you a quick reply ; you can look into running procmon to capture system calls to windows - launch procmon.exe and start capture before launching Plex media server - then stop capture after 3 minutes - save All as PML - zip and upload somewhere and send me link and debug server logs zip and I will have a look to see what underlying errors generated

Alright, thanks very much!

Plex logs are attached, process monitor log is available here:
