Hi, I have my youview box connected to a TP link ac1900 router via a Bt openreach modem. Everything works fine (free view, online content) via the youview box, except for BT sport where I get a message saying “please check your internet connection then try restarting your router. Check the connection between your box and router, then restart the router”. Given that everything else running via the router and modem work perfectly the issue must be with BT sport. Any advice?
