BT DNS flush

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

Have you tried turning off your router for an hour and turning it back on again?

I only restarted it briefly so I can try that.
Someone suggested resetting it but that isn't an option with the BT hub.
I'd just replace it at this point and use DNScrypt to avoid this nonsense.

Asking an ISP as a single end-user to effectively restart its full DNS operation is likely to result in nothing.

Some suggestions seem to be to turn on parental controls for the account and then turn them off again along with router reboots and resetting TV to its defaults.

I have reset the TV and tried the parental controls thing.
I'll switch the router off tonight.

What model is it? our LG lets you set the DNS server the tv uses (i use google 8.8.8.8)

Looking at his previous post it seems BT do not allow other DNS providers and intercept (and I assume change) results from other DNS providers.

you can not change the DNS servers configured on the hubs but as far as i know any DNS settings on the connecting devices overrides the DNS settings provided by the hub.

Are you connecting via your PC with wifi or ethernet connection?

Yes you can, I have setup a DHCP Server here and have disabled it on the HH and I supply googles 2 DNS Servers along with 2 of BT's common DNS Servers and our own DNS Server and I can see it using googles 8.8.8.8 in its return packets.

And also when I set the first DNS server as our own DNS Server (a Rack server located in a datacentre) I can see the requests showing up and we are receiving the exact same response packet.

So yeah, I say you can use other DNS Servers with BT.

It basically just tries to use the first DNS Server on the list and if that fails it tries the next and so on.
