@M1nnie doubt anyone can do more than guess but there are many customers with line issues following the recent bad weather. Log into the MY Sky app using a mobile connection aand click to run the connection test as it will check for known faults. If there isnt one call Sky and report the fault and they will get Openreach to check your line but it coukd take a while unfortunately.
