@Julienesbit Have you tried or checked the following, see the link below!
Try running the line test here to see if any faults are found:

You can also run the test via the MySky app on a mobile data connection.
Once completed, if it reports back that all is good click on 'broadband' to run an updated test. If you get amber or red you need to follow the on-screen instructions.
If you’re still having problems you may need to call Sky to report it. Dial 150 free from your Sky Talk landline (if it’s still working).
If you wish also see the link below and say what you see from that!
This link below provides information about the coloured lights on the various hubs that can help to see what is going on! If the system is also Full Fibre then the lights on the OR/CF ONT also require to be looked at!
