Cancelling stream after no data was received for 6s

Channels DVR Server Troubleshooting
#1

I am getting cancelled streams while watching live OTA on both of my HDHomerun devices (connect and quatro). Here is an example of the error:

2024/10/05 10:29:17.706782 [TNR] Cancelling stream 1072D5CE/0 ch15.1 after no data was received for 6s
2024/10/05 10:29:21.059991 [TNR] Closed connection to 1072D5CE/0 for ch15.1 KADN HD

I had this issue months ago and it appeared to resolve on it's own. Some additional information:

  • both devices are located in the same closet and are fed to a switch which is connected to the main hub in my office
  • all Channels connected players view over wifi. These are Firestick and Android TV device. All are affected
  • ChannelsDVR server is hosted on an i5 mini PC with 16GB RAM running as a Docker container. This PC has been running for over a year without issue
  • The station that is being tuned that cancels can be restarted immediately and can play for hours without an issue and then it can happen again but may also happen minutes later
  • Restarting the Docker container seems to lengthen the time between cancel occurrences but this may be coincidence

I am unsure how to even start to pinpoint where the problem lies. Does anyone have any advice?

Any help is most appreciated.

Im thinking an issue with your HDHR. If you grep your logs for "cancelling" you will see the same behavior for ch3 and ch 10.

Also seeing your signal strength at 100% for every channel. You may be overdriving the HDHR. They are very sesitive to that. You arent using an amplifier are you? If so rip that out of there.

I am 8 miles from my towers and I have to attenuate my signal 18dB to get it just below 100%.

This may or may not be your issue. It could be your HDHR. Investing in some attenuators wouldn't hurt. I'd buy like 4 of these (below) and then add them one by one checking your signal for all the channels. Shoot for 90-95% average on each channel.

Like i said it may or may not be your issue but it never hurts to pad your signal to get below 100%

Definitely looks like the HDHR is getting too hot of a signal.
That could be caused by cell tower interference where an LTE Filter would help.

Thanks to you both for the quick replies. I am using this antenna. I replaced a piece of garbage with this and I did have the amplifier enabled as I thought more was better and that 100% is optimal. I do have one channel that I watch that comes in weaker without the amp on but perhaps I can tweak that with some pointing adjustment.

Here's what my signal looks now with the amp off:

2024/10/05 12:45:52.095687 [SNR] Statistics for ch3.1 KATC-HD: ss=93%,92%-95% snq=100% seq=100% bps=6693176,237632-12857696 pps=573,22-1101
2024/10/05 12:45:52.095915 [SNR] Buffer statistics for 192.168.0.76 (Living Room FireTV Max) for ch3.1 KATC-HD: buf=0% drop=0%

Ironically I did have one of those LTE filters but I'm a dummy and I installed it outside and after a couple years and a really heavy rainfall it filled with water and stopped working. I'll look to get another one if this doesn't solve things.

Can't thank you guys enough as I was not even considering this as a potential problem. Will report back if I see the cancel with the amp off.

Spoke to soon. Same thing happening even after amp turned off:

I've edited this as the cancel happened again right after I posted the original occurrence. Not sure what to think now.

Are you using two HDHR Tuners, and if so does it happen on both of them?
I would try a new LTE filter.
Also make sure you totally remove the amp so it's not in the antenna coax feed.
You could also post on the SiliconDust Forum and they can gather diagnostics to help you out. HDHomeRun Hardware Setup & Troubleshooting - Silicondust

#7

Yes, both HDHRs are experiencing the same problem. I only pulled power from the amp. Both are still being fed through it as it does give me two outputs from the line coming from the antenna. I can pull that and connect directly. I am seeing a lower signal strength doing it this way.

How can I eliminate or somehow prove this is not channels specific? Do the HDHR have logs that might show something or is that what Channels is displaying in its log?

SiliconDust can see internal diagnostic data that we cannot.

Thanks for the advice. I posted there just now. Sidenote, the antenna I have does have 5G/LTE blocking so I don't think an additional filter would be necessary.

Something else to think about. If water entered that old LTE filer, it could have entered your coax cable. Not sure if you replaced the coax?

Televes makes great antennas

In your post over at SiliconDust you should mention what antenna you're using.

#11

The filter was at an amp outside. It would have taken a lot for the water to get beyond the drip loop going into the attic afterwards. That event happened last summer.

You are correct. The Televes is way better than what I had before. And thanks for the tip on mentioning on HDHR forum. I edited my post to include.

#12

The odd thing is I was having frequent cancels earlier after pulling the amp, I restarted the container and it has been stable since. It's been about an hour Same station.

#13

May just be a coincidence.
There were lots of signal type errors in your log (which come from the HDHR tuners).
SNQ and SEQ dips on multiple channels on different RF frequencies on both HDHR's.

#14

You defintely do not want to have that amp in line...

#15

Actually if he has the Televes Ellipse Mix Model 148883, it operates in pass-thru mode, bypassing the built-in preamp in the antenna, when the power source is unplugged. No need to remove the power injector/signal splitter from the coax. One of the nice features of most Televes antennas.

Correct. That is the amp I have. I only unplugged it.

#17

You may be asked to provide a RabbitEars.info Signal Search Map. RabbitEars.Info - Signal Search Map
Make sure you enter the height of your antenna above ground level.
You can actually zoom in to pick which part of your house the antenna in mounted on.
And enable the Shift Shown Location for Privacy

Can you tell me how to identify these signal errors in the log? Are they tagged the same?

My post on HDHR forum has not received a response. I do know this is the weekend and will try to be patient but I would like to try to get this sorted sooner than later as the live tv experience is getting pretty painful especially when watching sports haha

Here's an updated log. Can you tell me if you are still seeing signal errors? Note the last bit shows two back to back cancels.

Thanks guys!

If it is happening to both of your hdhrs then the common points are the antenna and the network. What does the networking setup look like?

#20

This is standard wired Ethernet with the playback on wireless firestick and android tv devices. I do not know how to test the network portion.
