I have manually done port forwarding. Roon now reports "Roon ARC can securely access your Roon Server" and "Your Roon Server was automatically configured to be securely accessible by Roon ARC."
But when I try to use Roon ARC, I get this message: "There's an issue with your Roon Server. Your Roon Server is online but there's an issue that's preventing access. Go to the Roon app for more information."
I can't see any more information on the Roon app.
Describe your network setup
Verizon FIOS router that I just configured for port fowarding.
We can see the phone connecting to RoonServer successfully via the open port, so port forwarding is working as expected. The problem is with the authorization - the session layer has inadvertently become invalid, resulting in a mismatch between RoonServer and ARC that prevents the latter from reaching the former. RoonServer can reach the internet through the port, and ARC can reach your router through the port, but RoonServer and ARC aren’t initiating a connection.
The hard solution is to reinstall ARC, which unfortunately requires you to re-download any locally-saved tracks. There’s an ongoing effort with development to prevent this condition from occurring. Some of these changes have been merged into the new ARC and Roon builds just released today.
So, I recommend trying the following:
Delete the ARC app
Update RoonServer to the pending update if you haven’t configured automatic updates
Re-install ARC - it will install the latest version automatically.
Let us know if this improves or changes the symptoms at all and thank you for your patience.
