Cannot access WD my cloud from Outside network


I have recently purchased a wdmycloud 4tb. When i first set the unit up I tested the connection from outside of the network using an iphone 5s and it worked perfectly. Since then i have tried accessing it on several occasions using 3G and through a broadband connection and it wont conect. I see a message saying the drive is not accessible. 

Is there something I am doing wrong?

Thanks for any help
