Time Machine Does not find My Book World Edition NAS

I have been using Time Machine for over 2 years with a WD My Book World Edition NAS (White Light WD10000H1NC). Recently the backups stopped. When I tried to reconnect to the drive I found that I could not located the drive in TimeMachine with what I thought was the backup drive name. Currently when I open Time Machine there is a share drive in list, but with a different name than I expected (WD_Backup on "bestback-backup") and when I try to connect to the drive it fails. I know the NAS drive is working correctly as I can connect to the drive in finder by mounting via "Connect to Server" with the name smb://bestback and I can see all my public folders. When I look in Finder I see two share drives, bestback and bestback-backup. However I cannot connect to "bestback-backup" and not sure how. I believe my issue is that the original backup, must be on the share drive bestback-backup, but not sure how to reconnect or remount it. I have gone into the WD configuration and confirmed the drive is named "bestback".

Try mounting the drive in Finder and then open DiskUtilities to see what shows there. Then use the First Aid tab and verify the drive.

I have the NAS mounted in finder and can access the drive files in "Public" with no issue. I can't run any DiskUtility on that drive. I also can't see the TimeMachine backup folders which leads me to believe TimeMachine is not looking for that specific drive.

Basically TimeMachine shows an option to connect to a "share" drive that I can't seem to mount. That same name appears in finder sidebar, but is "unmounted". I have tried mounting this other drive as a server using the name shown, but without any luck.

Not sure how to mount this other drive, which may be a folder or related to the original NAS. It seems like the NAS is partitioned or I need to mount to a specific folder within the NAS?

I found a solution and post in case it helps anyone. Seems like TM gets out of sync with the NAS.

Resolve by:

1) Unplugged drive from network

2) Turned off TimeMachine

3) Restarted Mac

4) Plugged drive into network

5) Selected drive and it asked me for user name and password

For some reason Time Machine would never get to the point of step #5 and prompt for name and password unless I went through this sequence.
