I get a similar thing with my HDHomeRun Prime…I have the Channels DVR and iOS apps. Not sure it’s the same but it always happens when one of my Apple TVs hogs the connection even though no one is watching. It would be great if you guys can add a timeout feature/option to close the connection after a period of inactivity. It’s the ONLY thing that my family complains about since moving to Channels and getting rid of cable boxes.
I was having the “Connection Lost” message every day from mid-April to early May.
I reviewed log from Channels DVR and HDHR Prime to find that it looked like an issue with the HDHR. I contacted Comcast because it appeared there was an issue with the MCARD. The MCARD came but I didn’t replace it because the issue stopped after 5/8/2018.
I didn’t realize I could look at the Channels app log on the Apple TV until now. Over the past week, I come home to the “Connection Lost” message when I leave Channels streaming a channel while I’m out of the house.
Today, It looks like it had no issues from 11-2 then the Channels log reports “The Internet connection appears to be offline.” yet within a few moments finds the DVR server and adds the tab back in.
Tuner sharing has been disabled or enabled and issues persist.
I’m operating with three Google Wi-Fi points and connected via Wi-Fi, but experienced the same symptoms when running on a Netgear Nighthawk X6 R8000 gigabit Ethernet connection. It doesn’t seem to matter if I have it connected via Ethernet or Wi-Fi. It has happened on all five of the Apple TVs I have in the house, Ethernet or Wi-Fi, obviously not all streaming content at the same time, but that points to something software OS or application level, IMO. I’ve literally changed everything about my network but this issue pops up periodically and I’m not sure where to go from here.
Where may I send the log?
That sounds pretty frustrating. If you’re seeing “internet connection offline” that’s coming from the OS. Are you google Wi-Fi plugged into another router or cable modem? What is handing out dhcp addresses in your network?
In the either case of Google Wi-Fi or the Netgear, DHCP was managed by the router, not the modem-router upstream. Also, for devices connected via Ethernet, they were connected through a gigabit switch, which was also replaced for troubleshooting.
I did submit a support request with Google as well, they cannot find any drops in network connectivity according to the logs, so they’re looking at something hardware/software related with the endpoints, naturally. 
I guess, now that I can see the ATV logs, I’ll watch those and see if I can get more detail or if it’s always the network being reported as the issue.

You can also try the VLC or InstaTV app to compare and see if it triggers the same problem. That would help narrow down to Channels vs tvOS
Hello. Lately, I’m getting Connection lost again. This happens only in Channels. All other apps are functioning while watching live TV. I can watch HD or SD channels and have the issue. It can happen in minutes or it can go for a couple hours then Connection lost. It does not happen in Insta or Plex, though Plex does this differently. I can also watch streaming apps such as Netflix or ABC or HBO for hours and not have a single issue. It seems to be something in Channels causing a fault somewhere to display the Connection lost message. When looking at the log, it all appears to be that the Apple TV has the issue with maintaining it’s connection but I find that hard to understand since all other streaming apps can handle the data stream volume without issue.
I look forward to your feedback!

All other apps use much lower data volumes. A typical internet based (or Plex transcoded) stream is 4mbps, whereas the raw HDHR stream is up to 18mbps.
You could change the Home Streaming Quality setting to force the DVR to transcode to a lower rate. That would mimic how Plex works.
I attempted to change the stream from original to anything else and it was choppy. When on original, it plays the stream without being choppy. I’ve got it set back to original again and since posting, I haven’t had the Connection Lost message even after hours of unattended playback. It’s so difficult when it cannot be reproduced with a specific action. Thanks for the follow-up!
I had this as well in particular with the HD DVB-T2 channels.. I could never figure out why it got worse in the evening and was fine in the morning. Turns out to be UK based 4G interference. Of course morning and during the day people where at work..
I resolved the issue by buying a inline 4G filter for £10 and haven't had any signal quality issues since.

Hi There,
In the last couple of weeks, I have started to get randomly lost connection errors and an issue where the video lags the sound for about 30sec and then catches up.
I have tried several things and what I noticed was when I turned off the DVR and only used the tuners connected to the channels app via my apple tv I had very occasional issues. As soon as I restarted the DVR it happened again.
I have deleted the guide data that is updated via HDhomerun subscription and then updated again it seems to have solved the problem. However, Im not convinced I have fixed it.
Can you help?
Update your Channels app to v5.2.1

Please submit diagnostics from the app immediately after it happens
Right now you have tuner sharing off so it's connecting directly to your HDHR
I see it tried to tune channel 2 but failed to get a response from your HDHR:
HDHomeRun: Could not tune to http://192.168.18.4:5004/auto/v2 after 30s -> Tuner Unreachable
Does the official HDHR app work on the same device?
Did you try restarting the tuner and making sure the firmware is up to date?

yeah I just noticed that and have turned tuner sharing back on. What is interesting is that I have not actually tuned into channel 2. I cn in the DVR that it saying activity "Watching ch2 from 192.168.18.3 (Remux Finished): strength=83% quality=94% symbol=100% rate=5.7Mb/sec". I have restarted the tuner and both apple tvs and still getting this?
I restarted the DVR and it seemed to release channel 2. Then I have selected a channel on an apple tv and that was fine. I then started to watch a channel on an iphone and as soon as I did that I got the connection lost issues again. I have submitted an updated diagnostic log if that helps
Ok, i tried the HDHR app on the same device and iphone and it does a similar thing. It crashes if I try to watch two channels at once.
I have updated the firmware on the Hdhomeruns
