Hi! What’s not quite right with Roon?

· None of the above quite fits

None of the above quite fits

· None of these quite match

Tell us what's going on

· Roon shows me that ARC is not available from outside my local network, but it is available from outside

Tell us about your home network

· I have nothing, no switches, no extenders, no VPN, nothing

If the reported status code is 530 and the error code is 1016, then this is an ongoing issue with the connectivity test that does not, as you have observed, actually affect ARC connectivity.

Roon ARC connectivity issue with "Not Ready" status (ref#L9A786)

Hello @Donald_Landwirth While Wade has provided an excellent and comprehensive guide on how to handle Double NAT environments, there is a specific detail in your diagnostics that suggests a different cause for this sudden failure. You are seeing “status_code”: 530 and “error code: 1016”. As you correctly noted, your setup has worked fine for two years. These specific errors indicate a temporary service disruption with the cloud infrastructure provider (Cloudflare), which is preventing our ser…

Hello @Claudio_Osorio

Thank you for the report, and thank you to Wade for jumping in with the correct diagnosis!

You and Wade are absolutely right. The “Not Ready” message you are seeing in Roon Settings is currently a false alarm caused by a widespread service disruption with Cloudflare.

Cloudflare handles the connectivity test that your Roon Core uses to check if the port is open. Because their infrastructure is experiencing issues, the test fails and shows an error (usually 530 or 1016). However, as you have experienced, your actual direct connection between the ARC app and your Core is perfectly fine.

What to do next: You don’t need to change any settings on your router or Core. You can safely ignore the warning message in Roon Settings until the cloud infrastructure is fully stabilized and the test can run successfully again.

Would you like me to go ahead and close this thread since your ARC is functioning, or do you have any other questions about your setup?
