Unable to login to web browser - Session Has Expired

I’ve recently bought a new macbook and I’m struggling to log in to the mycloud home web browser on my account - it keeps saying that “Session has expired. Please sign in again.”

Has anyone figured out how to fix this?\

Thanks

Trying checking your computer clock and time zone to ensure the time is not off or has drifted.

Unfortunately thats not it - the clock is set correctly…
