Roon nuc can't connect Imac over smb:// for backup?

Hi, I need some help.
I installed a Roon rock on a nuc today.
Everything’s going great, I’m pretty excited.
Now I wanted to set up the backup function, and it doesn’t work at all.
I have an Imac with an ssd connected to the Thunderbolt port.
On the ssd I wanted to set up the backup of the roon rock.
Everything is set correctly in the system extensions under file sharing.
I have also tried it with and without password.The reporting is allways wrong path.
Here is the path I have indicated.
Smb://192.168.1.1.11 or smb://192.168.1.11/Volumes/EXTSSDBackUp
Both variants do not work

Can someone tell me if I’m doing something wrong?

Thank you very much.

Sorry for the bad english I use a translation program.

I had the same problem a few weeks ago. Try to turen the file sharing feature off on your iMac and restart booth the NUC and your iMac, then, turen in file sharing agan.
