I'm not sure Virgin will even listen to us on this as it appears to be how they redirect customers to their Netflix cache (which works fine) and who knows what other caches, i know they used to do it with youtube aswell but i'm yet to notice an issue there
Looks like I'll need to figure out how to enable DoH via pihole then.

Assuming this fixes all of my issues. It is strange that this did actually work fine though.

is there anyway I can test my DoH - I've installed cloudflared, however using the cloudflare encryption test I get a question mark for DNS sec
