Access to NAS 104

Hi,

a few days ago I noticed that  my NAS 104 had a blinking blue led and also noticed that there was an error message which said out of memory 36c . I tried to access the device through the Ready Cloud but I couldn't get in to view the folders. I noticed that there was a message that there was no internet or that the device was swicthed off.  The device was not even visible on my network. I tried to switch it off but no buttons worked. So my only option left was to unplug the device. Bingo it worked. In fact after rebooting my laptop, at least I could see the folders through my network and the error message was gone, however when I tried accessing through the Ready Cloud, there was no way in spite of the fact that I was using the single sign in. In fact when I tried acessing through the Manage button a pop up window requested that I log in again! Still there was no way of accessing the folder through this method. A round about way was using the admin and password system. I checked the logs for any possible explanation but there wasn't anything which could have resulted in such a situation. Could anyone please explain how can I revert back to accessing the NAS through Ready cloud in a normal manner?
