Unable to access Local Admin Page

I encountered the problem of not being able to access using ReadyCLOUD (which is now known to have been caused by a Netgear issue) and after logging into the Admin Page I did turn ReadyCLOUD back on - this was last week sometime.  Once I did this I was able to view and access the shares once again and have access to the files I was looking for.  Fast forward a couple of days, when attempting to go back to the Admin Page I am now getting the following error when selecting Manage | Admin Page from the readycloud.netgear.com address:

Local Admin Page

The Admin page can only be accessed when you are in the same network (LAN) as your device

So I tried accessing via the IP address https://10.xxx.xxx.xxx/admin and here I get the message:

Forbidden

You don't have permission to access /admin on this server.

Apache/2/2/31 (Debian) Server at 10.xxx.xxx.xxx Port 443

The ReadyNAS is now running firmware 6.6.1 and shows as being healthy but at the present time I cannot manage it.

Both computers I have used (one a Mac and another a Windows) are on the same network and both show the same issues.  Any suggestions on how to gain access to the Admin Page so that I can manage this device?

Thanks!
