I tried playing with private address setting on apple watch, turn it off/on. Reconnect, reboot. But it doesn't change anything.
Is there anything other I can try?
I still have no idea which domain is blocked
If you don’t use pihole it works fine
And as I have network issues, I am using my router DNS at the moment
Funny thing I found is problem remains if changes are revered and pihole is not used.
I reverted back to my original dns server (router ip) - and still this problem.
Everything back to normal only when I am on cellular data. So I would assume it is something on iOS level, some cache or something. I really do not want to try resetting network settings, will wait a day to see if anything changes.
