Hub 4 been flashing red all day.. have reset it and everything with no luck

As per headline.. all day flashing read and ive left it all disconnected for 10 minutes and pressed the reset button in the back in hope that would fix it..

any help would be most appreciated as i really need it back up and running :-(

I cannot remember the last time i had any problems with it.. been brilliant to be fair but it is having none of it whatever i try :-(

Tried the service status and it says no problems
