My access to BBC iPlayer was stalled/blocked on iPhone (iOS 10.3.2), other web access using pihole was fine, iplayer on OSX + pihole fine too. I ran around in circles, ran:
No change.
pihole -v
Pi-hole version is v3.1.4 (Latest: v3.1.4)
AdminLTE version is v3.1 (Latest: v3.1)
FTL version is v2.10 (Latest: v2.10)
My sense is that this started after last iPlayer update. 4Sep2017 v4.32.0, which forces us to register/login.
Getting frustrated, seems odd that no one else is getting this (Google throws up zilch)
Rebooted iPhone: iPlayer restored!
