Cannot access My Cloud cross subnets

I cannot access the My Cloud EX4 devices Web Control Panel from different Subnets.

Why is this, and how can it be resolved?

I get the error message:

403 - Forbidden

This device has been bought to do enterprise work, no matter where you are.

Does anyone else have this?

Found solution:

My default, the My Cloud EX4 will not serve the administrative web interface outside of it’s local subnet. This can be changed, by going into Settings, General, then enabling the Dashboard Cloud Access.
