After the initial setup of a Nucleus (Rev B), I was able to successfully get ARC for iOS functioning properly. However, the Roon sotware, be it from my Mac, a Windows laptop and my iPhone 14, would instantly crash. I was able to access the Roon Core on my Nucleus via the web interface (by punching in the IP address in a browser). I quickly found that the Roon Core OS build/software on the Nucleus was outdated. Because I did not have access to the Roon software, I had to update the OS using the web interface. There was some warning about using this method as a last resort, because then I’d have to reset ARC. Sure enough, once the Nucleus was updated to the latest build, I could no longer access ARC, be it from my Mac, nor any iOS device. Any network settings i.e. firewall, antivirus or the like, were unchanged from when ARC was working, so I do not believe it has to do with something “external” but only because I updated the Roon OS/sofware. Note that I did go through the recommended troubleshooting steps (including port forwarding), to no avail. Since it was functioning correctly when the Nucleus Core was running on an earlier build, I’m guessing that ARC has to be “re-synced” to the Nucleus once again.
