Just submitted diagnostics, when I turn on the Apple TV from sleep and channels was the last app in use it will many times say that it can't connect to the DVR then connect after a few seconds. But afterwards it goes to the On Now section instead of recordings that I have set for both startup and resume.
Welcome to the club. I’ve been experiencing this on iOS for awhile now. Are you running Ubuntu on your server?
No I'm on Windows 11 and everything is hardwired ethernet, no other issues with network.
