This’s getting unacceptable.
My HA runs in a network where all traffic must go through my own DNS server to avoid DNS poisoning, thus any other DNS requests is blocked or redirected.
I wasn’t aware of the situation before this post and it explains A LOT why HA’s been countering some weird network issues.
PLEASE DON’T force people to use embedded DNS, cause google devices do and they’re a such a pain in the ass.
