Your diagnostics show “status_code”: 530 and “error code: 1016”. These errors indicate a temporary issue with the cloud infrastructure provider (Cloudflare), which is preventing your Roon Core from successfully running the connectivity test.
Because the test itself is failing to reach our servers, the “Not Ready” status and the UPnP errors you see might be misleading. Your actual connection configuration may be fine.
Please try this practical test: Ignore the error message in Roon Settings for a moment.
Disable Wi-Fi on your phone (switch to 4G/5G).
Open the Roon ARC app.
Does it connect and play music? If it works, you can safely ignore the error message while we resolve the server-side outage. Please let us know the result!
Different IP address but same issue. Error message in Roon to validate ARC functionality, but in Android ARC App everything is working fine outside my home network - music is playing at 5G
In addition to my posted error message, I saw another message in Roon stating that there were problems synchronizing metadata due to server connection problems. Resolving this needed a reboot of my NUC and Router.
After completely reconfiguring my router and smartphone (even though I hadn’t changed anything for months), I saw in this post that you are already aware of this problem. Next time I’ll look at the community first
