Pasting from a reply to an hdhomerun error that looked identical.
I have the same issue with an avermedia volar hybrid q usb.
Detects it, asks me to scan. Hit cable scan and it actually does a (useless) scan. But if i leave the proper antenna selected and hit scan it gets to 0%, sits for 10 seconds then dumps out to an error. I’ll attach a pic.
Once this happens plex must be crashed/exited and reloaded before it will “find” the dongle again. If i just try a 2nd scan it will not initiate it (after switching cable/antenna as well).
The oem sw package (newest dl) is goofy but it did proper scans and spit back 50-60 channels (I’ve got a few that like to hide, apparently).
Plex appears to be asking the volar to or for something it don’t like, causing it to crap. I do not feel like diving into the hell that are the plex logfiles to verify this - it’s obviously borked atm tho.
Fresh cap card install, freshest driver/package. No firmware upgrades in sight.
w10 x64
nvidia updated
plex pass and the qam nightly tried
Without logs, theres not much anyone can go on…
Under Help there’s a ‘download logs’ button, you can click on it and just attach that zip.
i just wiped the logs and duplicated the issue.
any help is appreciated. thanks!
I can confirm the exact same behavior from the exact same setup as @Beelzebozo . I’ve attached my logs as well, would be very curious to know if there is resolution to this.
Thx for the verification, sedvideo
I did have some goofy intel chipset driver issues. No idea if fixing them made any difference… but i poked through windows logs and was aghast at the red 
dumb crap but one was some kind of TPM-type call and, who knows… maybe plex ■■■■ because of some goofy drm related issue. Also upgraded the so called bios (i remember when those actually let you, you know, do stuff)
Dell xps 8700 (i think) btw. Seems highly unlikely… but i just can’t will myself to try to decipher the plex logs.
No biggee but i want to get it sussed relatively soon
I just checked the logs myself.
As expected, the “tuner service” is crashing and flinging out a crash report. Everything seems fine… then it gets to some point (after i hit scan i assume) and it craps out.
In the oem tuner package the software likes to refer to the “antenna” as “antenna qam” or something odd. Idk if it’s jumping into some weird unsupported-by-plex mode or not. As noted i did try qam scan in plex, which does run but “correctly” finds nothing.
I can probably run a splitter off of my cable modem (i say probably… idk how touchy the signal is to hijacked lines) and see if comcast sends anything in the clear. No friggin’ clue but, knowing comcast, they encrypt even the shopping channels
Bundled sw package makes me ill, btw. Dollar an hour code farm garbage.
I noticed in both your logs that Plex Tuner Service showed this error:
Jun 06, 2017 16:59:34.214 [13600] INFO - * web_server_t::start. Starting web server on port 32600
Jun 06, 2017 16:59:34.218 [13600] WARN - [E] web_server_t: bind: Only one usage of each socket address (protocol/network address/port) is normally permitted
Jun 06, 2017 16:59:34.218 [13600] WARN - [E] web_server_t: port 32600 is not available
Which would make me think there’s multiple copies of Plex Tuner Service running…
So this is what I suggest:
Stop Plex Media Server entirely. Verify there’s no ‘Plex’ processes in Task Manager.
Go through your system and make sure nothing could have taken the capture output. Maybe Sound Settings? TeamViewer? Any application like this.
Then start up Plex Media Server again.
Now can you scan?
@keithah
I’ve done what you suggested, went through the task manager to close out any potential conflicts with Plex seeing the tuner card, if I am understanding correctly, and I still have the same issue. Do I check to see what exactly is addressing port 32600? If so, how do I do that?
Thanks for the assistance btw.

Quit Plex Media Server and see if there’s any left over processes of Plex Tuner Service in Task Manager. If not, start it up again and see if Plex tuner Service says that still…
@keithah
Just shut the server down, task manager said no Plex Tuner Service running. The only Plex service running was Plex update service. Restarted the server, and PMS, PMS DLNA Service, Plex Tuner Service, and Plex Update service are running in Task Manager.
Can you post your Plex Tuner Service log after all this?
@sedvideo also can you open up a command prompt window, run “netstat -an” and paste the output to gist.github.com or pastebin.com and link the results here?
plex… likes to crash while streaming. this is an ongoing issue for me. it happens if i seek a couple times in a row and possibly when i jump to another show. it’s the transcoder not cleanly exiting a previous task. well - maybe not the transcoder per se, as it seems to happen in “original” streams to other devices including win10 laptops (and i don’t think the transcoder is touching the file). if I’m paying attention then toggling a lower bitrate or hopping to another file seems to flush the runaway cache/transcode from plex. if I’m not and i just hammer seek a few times i can usually get it to a state where plex crashes pretty well outight and i need to kill tasks and reload it.
tuner “scan” is similar - once i hit scan i cannot rescan until i kill the service (i am 99% sure that a std graceful exit plex doesn’t work). these are separate issues in that the tuner is quite new and the cache/transcoder issue has existed (for me) for a long time. i live with the latter, though it’s annoying.
I’ll do a netstat in 1 minute
@keithah
attached is the results of the netstat. I hope I did that correctly, never used pastebin before. Let me know if I need to do something differently.
Also, how do I post the Plex Tuner Service Log? Is that different than the regular log file? I’ve attached that as well.

@Beelzebozo
I too have the same issue with the scan. It locks me out of the scan after the first try, have to restart the server for it to see the usb stick and try the scan again.
Not a big fan of the software that came with the usb stick. It looks utterly ridiculous, but it does see the over the air signal from the antenna and plays the content in the interface. Just doesn’t seem to be sending that info over to Plex the way it should. Interesting dilemma.
netstat has no references to github or pastebin… or any urls, for that matter. it did have some ipv6 stuff that made my eyes bleed.
i dumped it to a text file and you can take a look, if you like. over the port you mentioned I did see some open/waiting connections made by plex. the only thing that looked odd (i guess) was
[Plex Media Server.exe]
TCP 192.168.1.42:32400 NCC-1701:49494 CLOSE_WAIT
which would be a loopback (i think… both sides resolve to the same box, at a minimum)
not sure what youre looking for over github/pastebin… i do have vmware installed, which slaps its netswitch in (plex is not running boxed). also may have an nvidia “who effing knows” network helper in between the card and the world. if so it’s the standard install.
Let me know if there’s more you (all) need or want me to try.
Same problem here. :neutral: Won’t scan for channels.
