HDHomeRun Connect in Plex. Device not found

Hi All,

I have the following error on my Plex server when using HDHomeRun Connect.
“Device not found. Ensure your device is powered on and connected to your network.”
Live TV works on iOS but not Android.
Please advise if you know the reason why. Thank you so much.

Is the hdhomerun in the same subnet as the Plex server?

i have a the same issue after initial channel scan, all shows appear to recording properly server is 10.10.0.xxx and tuner is 10.10.0.xxx subnet of 255.255.255.0 wonder if this is related to some shows not appearing in the guide?

They sound like two different issues I think, op cannot find device at all, sounds like plex saw your device at some point? Not sure whay is happening wiyh yours, Have you updated firmware, checked the channels from an app outside of plex?

Yep I’ve run into this a number of times. After a few days of working perfectly fine I’ll get this error in my Plex DVR setup. During that time nothing has changed in the network and even the IP addresses of all the devices are the same as I have them under DHCP reservation.

To fix the issue only I need to do is quit the PMS on my Mac and start it again and bingo fixed. Interestingly restarting the the HD homerun has no effect, only restarting PMS. Also at no point do any other apps (e.g. channels on my Apple TV) have trouble finding or communicating with the HDHR so it’s something to do with PMS losing the plot.

Yes they are on the same subnet

I use the same subnet 10.10.10.xxx. Initial scan works fine. Plex recognized the HDHomeRun device. But then it keeps giving that message “device not found…” I wonder if I have a defective HDHomeRun Connect or this is a flaw with PMS.

I think it is the same issue. I tried everything, update, restart, reinstall, rescan, use dhcp then static ip. None worked. PMS sees the device initially but then gives “device not found…” message again.

Same problem I am having. Except even with restarting PMS, it sees the device but then lose it moments later. Although, just like you described, other apps have no problem finding HDHR.
Probably this is a glitch?

I found a good deal on an HDHomeRun, and finally got around to setting it up today and have the same issue. It works fine, then loses the connection. I am able to stream just fine from my iPhone’s Plex app, but the server setup shows that it can’t be found.

I haven’t been able to figure out what causes it to start throwing this error.

Here’s my setup

Fedora Atomic version: 26.91
Plex Docker image: plexinc/pms-docker:plexpass
Plex version: 1.8.0.4109
HDHomeRun firmware: 20170808beta2

I recently started having the same problem. I have two HDhomerun connects. They were both working fine then suddenly only one shows up on plex. I tried connecting and it’s not found by plex. I tried manual installation by IP address and still nothing. Other devices still see both HDhomeruns on the network.
