Trouble with Time Machine on Synology DS413?

Hello All,

I've noticed recently that Time Machine quit working on my mid-2010 MBP that keeps updated to the latest OS patches and updates. Has anyone else noticed a problem? Did something change in the OS?

The computer can't see the share on the NAS, and it was working fine not that long ago.

I'm not too worried about it, because I keep all files on the NAS anyway, but I thought I'd ask the group.

Thanks in advance,

Tom
