Can you let me know if you have updated the Synology to the newest firmware version? There have been a few similar reports contained in this thread: No longer connecting to SMB shares on Synology via Hostname. It is not clear yet if this is due to a Synology firmware update and we are investigating.
In the meantime, if you try to use the IP address instead of Hostname, does the connection to your Synology work? IP address format can be used according to our Add Folders By Path Guide, e.g. \\IP_ADDRESS_OF_NAS\Multimedia\music or smb://IP_ADDRESS_OF_NAS/music
If you do have the NAS share via IP address, I would suggest performing an address reservation in your router to ensure that this IP address does not change.
