RS250 SSD not found by Roon

After successful installation of a Samsung 870 EVO I was able to load HighRes Music Files from my MacBookPro M1Pro to the RS250 SSD and play all files via the streamer. Using Roon I was not able to find the SSD. All attempts to connect Roon in ‘Settings, Storage, Folders, add Folders’ to the SSD failed. My Auralic Altair G1 was not easy to but could be connected to the Roon Net.
It seems as if the the address-line in settings is very critical to even the smallest changes. I used ‘rose’ as ID and ‘rs250’ as PW.
Hopefully someone can tell me the exact line I have to write in the add folder.

Hi.

In my case, disk installed in RS250 and with smb activated (on) in RS250 settings.
In Roon on MAC the route that works for me is: smb://192.168.1.77/ROSEDISK

You have to put your own IP from your RS250.
ROSEDIK is the default name of my shared disk.
