At a glance, It looks like you need to visit the App Store and download Roon 2.0 for your device. This of course doesn’t affect Arc but will be a problem down the road.
Can you describe your networking setup? Did you have a chance to visit the guide below and implement the necessary networking changes for port forwarding?
Yesterday I made few km on the car and was able to play local files. I live in Barcelona, Catalonia, Spain and I am now for Holidays in Saint Cyprien, Rosselló, France
I can see that your core has been offline for about 18 hours now. Can you please navigate to your core’s WebUI and see if there’s an issue? Perhaps the IP Address changed? If that’s the case, you may have to go into the settings within ARC and Reset Roon ARC (which happened to me this weekend).
I received a message from my Internet provider (Spain, Virgin Telco) I was included in CG-NAT (again)
Under this rule you cannot redirect anything as no single external IPV4 address for connected device, but shared one for all…
A rebooted router after coming back to CG-nat and back to the first scenario. Sometimes, sometimes not.
Tomorrow I will connect (test scenario) my NAS with stored music on the same switch and place than computer running ROON and I will see if when available by Tidal my local files will be available, too.
Down to my kness and I am begging you/Roon teammates/clever users for your pardon.
Today I took my NAS from its place (PLC connection with no issues at Home usage) and connected to a switch cable wired to router, same router has a direct cable to Roon core PC.
Flawless
Reproduces everything, my storage or Tidal files.
Under WiFi or under 4G
Astonishing
Now I have to decide what to do but clearly the cable connection is the best option in my (many) cases.
