This may be of interest because, perhaps like on my Roon server, the Arc Port was NOT set to the standard value automatically - on my Roon server it was a completely different port number which I don’t know how it got defined…
Changing the port to 55000 (and ofcourse since I defined the port forward in the firewall with port 55000 as per the Arc configuration FAQ) resulted in a working Arc. Yay!
My experience exactly. Arc is a game changer, just need to change the name to Roon Mobile. ARC is particularly useful since I have items in my collection that aren’t available through traditional streaming services. Big Kudos to the Roon staff on this release.
Same… it was 41909… but not sure why that didn’t work when I had all my port forwarding set to it. But manually setting to 55000 and doing the port forwarding again it worked.
ARC doesn’t care whether your Roon Core (or, more likely, your home router) has a DNS entry. It presumably gets the IP address by querying Roon’s servers.
I don’t think so based on my experience; it seems it updates the address + port it’s available at when you’re in the ARC setup box. So DDNS itself won’t help - if your IP changes, you’ll need to open that setup box again for it to update your available address. Not confirmed - just my present experience.
