Syncing has stopped with WD MY Cloud

I set up WD syncing on this W10 PC some time ago and have realised it hasn’t sync’d for several months.
Clicking the WD Icon there is a message saying ‘WDMyCloud’ is missing. I can’t determine exactly what this means,
The connection to the WD device is OK, Firefox brings up the WD control panel through the IP address.
Any advice would be welcome


Are you sure you own an My Cloud Home? If not an MCH, then what WD device do you own?
