@Isabella99 the standard advice is to check the lights on the the hub which you have done -see https://www.sky.com/help/articles/hub-lights-explained-start - If they show the hub has lost connection to the line and a simple reboot doesn't sort the issue is to log into the My Sky app and see if the service checker tells you Sky are aware of a fault affecting your line. Don't worry if it says everything is fine as that was the position when it last tested the service.
If it doesnt tell you it's a known fault call Sky their lines are open from 8am to 9pm
