MDNS lookup Error

[Raphelchen]

What to investigate?

I have an AppleTV in my network. It used to work fine up until a few weeks ago (I guess after an update of the AppleTV). Now, it gives me a bunch of MDNS lookup errors before it finally finds it. But this behavior produces error in the rest of my code, and i would like to find out the root cause of this, rather than trying to adjust my code.

When i scan for the atv, i get:

(There is more, but i don't know how sensitive this info is, and would rather leave it out if possible. I can of course add the relevant Info, if needed)

At this point, the AppleTV was found in the network with the necessary protocols, and i can use it then in the script.

I'm running this script on a raspberry pi, with PiOS Debian GNU/Linux 12 (bookworm)
pyatv version 14.5
python version 3.12.0

I would appreciate a pointer to the right direction, where to look, because i can't really find much on this atm, other than this other investigation, that got magically fixed.

Expected outcome

connecting with the AppleTV without getting MDNS lookup errors.

That'a a bit odd, not sure what the root cause is. Can you re-run with --mdns-debug?
