Time Machine Can't Access the backup disk on my Synology NAS after upgrading to El Capitan OS X

I tired upgrading my MacBook to El Capitan OS X this weekend. I kept getting stuck at the loading screen with the bar only 3/4 of the way through. I tried multiple attempts at reinstalling and even tried recovering from a Time Capsul backup to no avail. I then went on ahead and erases the volume and reinstalled El Capitan OS X. However now I am trying to restore my progress and files from my NAS. When I open Time Machine and try and set it up, it gives me the message

"Time Machine Can't Access The Backup Disk "TM". The operations couldn't be completed. (OSStatus error 2.)"

I can access the NAS by typing in the IP address into the Safari Window, but can't seem to get Time Machine to access it.

MacBook Pro (Retina, Mid 2012)

Processor: 2.6 GHz Intel Core i7

Memory: 8 GB 1600 MHz DDR3

Graphics: Intel HD Graphics 4000 1536 MB

Just trying to be able to access my Time Machine backup so I don't lose all of my pictures...please help!!!!!!
