Android TV app loses connection - disastronaut

[disastronaut]

After the recent firmware update, each of my devices can only keep connection to the HDHomeRun device for a maximum of 30 minutes. If it finds the device on the network at all. After clearing the Android app's cache, it can find the device and works for a few minutes; but then we see a "unable to play channel: communication error" which will not go away until we clear the cache again. Even clearing the cache can be hit or miss. Sometimes the app will take us to the "Recorded" section with no option for live TV. Other times after we see the "Communication error", we navigate back one step and see the list of shows in the "Discover" section, which leads us to believe there is a some kind of data being sent back. We didn't change any settings or the network configuration until a few days after the firmware upgrade when we started trying to fix the issue; so hopefully our network isn't the problem. Speaking of which, when looking at the list of devices on the network, the hdhomerun will occasionally pop in and out. None of this happened before the recent firmware upgrade.

Here's the list of troubleshooting steps we've tried so far with the same result:

1. Turn off IPv6, restart Wi-Fi in Android TV, clear cache, start app
2. Turn on IPv6, restart Wi-Fi in Android TV, clear cache, start app
3. Restart router, start app
4. Restart router, restart Wi-Fi in Android TV, clear cache, start app
5. Restart router, restart network switch, start app
6. Restart router, restart network switch, restart Wi-Fi in Android TV, clear cache, start app
7. Connect to a different SSID, restart Wi-Fi in Android TV, clear cache, start app
8. Check system log, change some settings in home DNS, restart Wi-Fi in Android TV, clear cache, start app
9. Temporarily change DNS in Android to Cloudflare, restart Wi-Fi, clear cache, start app

The reason I started messing with the DNS is because I saw this line consistently in the system log:

Code: Select all

20231227-01:05:00 System: myhdhomerun_sync: webclient error (dns failed)

I didn't see anything related to silicondust or hdhomerun blocked on my network; so maybe it's on your side? If it helps, I have a Pi-hole attached to the router. Like I said in the list above, bypassing the Pi-hole didn't make a difference.

I've turned on Diagnostics. My device ID is 10804844 and the firmware version is 20231214.

If it helps, there was a communication error at 2:00 PM UTC and 12:50 AM UTC on December 28th.

It looks like a bunch of new trackers are being blocked by pi-hole. Any of the following domains below required by the guide server?

• cdn.taboola.com
• a.teads.tv
• aamt.nbcnews.com
• a.pub.network
• aan.amazon.com
• aax-us-east-retail-direct.amazon.com
• aax-us-iad.amazon.com

Let me know if you need anything else.

Do you have a way to get a Wireshark/tcpdump capture of the HDHomeRun doing the DNS lookup and failing? Port mirroring if you have a managed switch that can do it, or a PC with a couple network interfaces bridged together, one with the HDHomeRun plugged in and one going out to the rest of the network?

[disastronaut]

I can post a tcpdump. The network switch is very basic and only really functions as a way to increase the number of wired connections. Not sure port mirroring would still be helpful in this case. I can try if needed but I haven't had to set up port mirroring before.

The communication error happened at 09:44AM UTC. Let me know if you need another tcpdump.

[disastronaut]

Any chance the connection is being lost when trying to periodically contact the guide servers? I saw some logs in the tcpdump saying there was a "bad udp checksum" when trying a backup DNS.

[jasonl]

Need to get the capture of what's coming and going from the HDHomeRun, and it looks like this is what is coming and going from the pihole. Port mirroring allows another device to monitor everything coming and going from the HDHomeRun, because without it the switch only passes the traffic from the HDHomeRun out to the port that it needs to go to, not to the rest of the ports. If it's an unmanaged switch or otherwise doesn't support port mirroring, the other option is to use a computer with 2 interfaces bridged together to basically act as a man-in-the-middle and record the traffic at that point.

[disastronaut]

Quick update: I saw in an old forum post where a user thought the network was the problem but it was actually a failing power cord. They didn't realize it was a problem until a system upgrade was needed and the HDHomerun restarted. I ordered one about a week ago and it should be here in a few days. If the issue persists, I'll set up the network bridge to record the traffic.

[disastronaut]

New power cord didn't resolve the issue. Which is expected I guess. Kind of a shot in the dark anyhow. I'll try to figure out bridging the connections since the network switch is not managed.

[disastronaut]

Also tried a new network cables but no luck. I'm having difficulty bridging the connections; so I tried Wireshark to watch network traffic on the hdhomerun. Here's the output from around when the connection error happened today:

I have the diagnostic mode turned on too if that helps. Device ID is in the original post.

What OS is running on the computer that you're trying to bridge the connections on? The text summary from Wireshark isn't really useful.

[disastronaut]

Windows. The issue I'm running into is only having one network connection so there's nothing to bridge. Should I try to create some virtual network connections? Any other software or tools that could help? Sorry I'm not much help. Networking isn't my strong suit.

[jasonl]

You need a computer that has 2 network interfaces. Should work with wifi+ethernet, or onboard ethernet+USB ethernet, or something like that.

[disastronaut]

I realized after posting that I could add another network connection with an adapter. Bridging Wi-Fi and and ethernet didn't work; so I'm going to buy another adapter to bridge the internet connection coming in with the connection going to the hdhomerun. Once that's done, I'll try bridging those two ethernet connections and exclude the Wi-Fi connection since that caused network problems. Thanks for your help and patience!

[disastronaut]

I was able to set up a network bridge but wasn't able to connect to the hdhomerun on the network. That part is still a work in progress.

I've been trying hdhomerun on different devices and Android is the only platform I own having issues. Using hdhomerun on Windows and on an old Apple TV seem to work fine but Android throws the communication error consistently. Even after upgrading to the new Android TV version.

Hopefully I can figure out how to bridge the two connections and see the logs as the error is being thrown.

[jasonl]

Start menu > search for and open Control Panel. Set the view to Small icons, then open Network and Sharing Center. Click Change adapter settings on the left. Highlight the 2 interfaces, right click on one, and choose Bridge Connections. This will create the bridge, and the HDHomeRun should pick up an IP on your main network and be accessible to everything, and you can point WireShark at it and it will be able to see everything coming and going.

[disastronaut]

Thanks for the steps for creating a network bridge! I was able to figure that part out already but was receiving an error during the creation of the network bridge. If anyone else reading this sees an error saying "An unexpected error occurred when configuring the network bridge" (very descriptive error), try removing one of the connections from the bridge and then adding that same connection back to the bridge; but don't remove the bridge entirely.

I have wireshark watching the network bridge but now the communication error is playing hard to get. Which is a good thing but bad for troubleshooting. Now the HDHomerun can go hours without an error. I wonder if having the HDHomerun on different internet source solved some sort of feedback loop in the switch. Or a successful phone home to the guide servers was needed? I'm basically spitballing trying to figure out why it's working all of a sudden. If the device(s) continue working then I'll reply again saying to close the ticket.
