Hi @Neil_Perryman,
I was looking over your previous threads and it appears you’ve raised this issue a few times, see:

In the second thread you seem to be using smb://IMAC-2.local/neilperryman/Music as the watched storage location and you mentioned this worked in the past. Does that by any chance work?
It seems like your network might have trouble resolving an address from just a hostname, I would also try rebooting the Nucleus and you networking gear as well.
