Netflix only working on mobile devices

[lmpinky85]

Hello 

I am having issues being able to watch Netflix on my tv's, sky box and fire stick. I can only watch it on my mobile devices through both WiFi and mobile data. I have spent 3 hours online with both Netflix and Sky trying to resolve this and have tried all of their suggestions but still nothing. Several error codes coming up which points to network issues but sky have said everything is ok. Any ideas please? 

Just to add - Netflix isn't through Sky.
