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

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.

Is your Shield outputting 4K30 or 4K60? I used mine quite extensively for sports before it died and didn't see any issues with it running at 4K60.

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 HD...

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?

There was a bug in the part of the DVR code that handles the communications between DVRs that is used to decide which one will make a particular recording.

This may not be the correct topic to post this question, but I figure I would start here. I am running two instances of this Docker container. One on my unRAID server, and the other on my Synology NAS. Both are running version 2.1.0 of the HDHomeRun DVR Manager, and Record Engine Version 20231020. ...

Windows or Mac?

I think the only way to get any further on this would be to get a packet capture of what is going in and out of the HDHomeRun when this is happening. Do you have a computer that has 2 network interfaces, either 2 wired or wired+wireless?

Is the connection on/active 24/7 or does it get shut off when not in use?

Who is your ISP and what type of connection is it (cable, DSL, fiber, LTE, satellite, etc.)?

What router are you using currently?

During normal operation, approximately every 8 hours, the HDHomeRun connects to our server and sends in the data for the channels that are currently enabled on the device, and gets a key back from the server. If it is unable to communicate with the server for some reason, it retries about every 10 m...

The HDHomeRun did reach the server at 20:55 UTC this evening, so that part of things is working, at least tonight (I don't have a way to see what might have happened previously). Can you re-enable the sending of diagnostic data in the HDHomeRun app and close and reopen it? Would like to see what the...

I use Cloudflare DNS, 1.1.1.1/1.0.0.1. Strong privacy policy and better performance than alternatives like Google DNS.
