I'm having an issue with just Netflix on a Samsung TV where I get error UI-113.
All other streaming apps work on the TV and Netflix works on all other devices.
Netflix also works fine on the TV if I use my iPhone as a hotspot using Vodafone 4G so the issue appears to lie with BT.
This is also what Netflix have suggested and told me I need to ask my ISP to flush their DNS cache.
I know BT intercept all DNS request which makes sense as changing the DNS provider on the TV makes no difference.
Anyone know of a fast track method of who to talk to in BT as their first level support in India pointed me towards another paid for service to help me set up the TV
