Unable to Connect on Mac Device

Interesting sistuation. I've had our NAS for a couple years, went out of town for a week and after I returned the NAS dodn't auto connect in FInder. Tried to reconnect, nothing. Opened ReadyCLOUD, it states device is offline. Tried on iPhone in ReadyCLOUD app and received message device is offline. The interesting part is my wifes Mac is still connected. I can acces the folders and files on her Mac, just not my Mac. Any suggestions? 

Both are running same OSX version, cannot figure out why my Mac cannot connect.
