Volumio 3.165 on RPI3
NAS drive mounted on openmedia server on RPI4 V 5.6.21-1 (Usul)
Wired ethernet connection
After update, the startup wizard successfully detects all of my network drives and appears to be configured identically on the sources page as my other volumio 2.xxx in another room.
On trying to save error message is as follows:
Error: could no resolve address for [NAS name], unknown error.
Any assistance will be gratefully received
