Lightroom and Synology NAS

Anytime my Mac has been restarted, I have to reconnect the images folder in Lightroom with my NAS-Location. Why is that? It should have access once it has been setup the first time.

On my NAS I have a folder IMAGES...this folder is connected in Lightroom properly (green status). I restart my Mac, I enable the network SMB connection (CMD + K). I have access by Finder to the IMAGES folder. Then I start Lightroom and the IMAGES folder is disconnected. I have to reconnect by updating the folder location.

Is there a way to get this better working?
