Roon ARC app connectivity issues (ref#P0G401)

[Mikael_Ollars]

Hi! What’s not quite right with Roon?

· Can’t reach my Server, remotes or ARC

Can’t connect to my Server, remotes or ARC

· Other ARC issues

Tell us what's going on

· I thought the outage concerning ARC was solved, but i still have issues. I tried to initialize the ARC app on my phone from another LAN than my home, but was unable to initialize the app. (Error message was something in the vein of "couldn't sync database"...
When back at home init is successful, as well as some downloads.
In the regular Roon app, ARC section still reports connectivity issues though:
{
"ipv4_connectivity": {"status":"NetworkError","status_code":530,"error":"error code: 1016"},
"external_ip": {"actual_external_ip":"213.aaa.bbb.ccc","actual_external_ipv6":"null","router_external_ip":"null"},
"natpmp_autoconfig": {"status":"NotFound"},
"upnp_autoconfig": {"status":"NotFound"},
"multinat_autoconfig": {"status":"Failed","error":"No uPnP Routers found on LAN"}
}
I haven't tried accessing my media from a public network yet, but the diagnostics should not fail in either situation.

Tell us about your home network

· It's... ...good...

This is the cloudflare issue that is all over the forums and the pinned post.

It doesn’t mention ARC, and it’s a guessing game as to whats affected. Figured a report might be useful either way.

Roon ARC will work despite this message.

Hello @Mikael_Ollars

DDPS is absolutely correct here. The specific error codes you are seeing (530 and 1016) are the hallmark of the current service disruption with the cloud infrastructure provider, Cloudflare.

This error prevents your Roon Core from verifying its connectivity status with our servers, which is why it reports a “NetworkError” even though your actual home network configuration is likely fine.

We are monitoring the situation closely. You can keep an eye on the official status here: Roon Labs Status Page

Once the incident is resolved on the Cloudflare side, your ARC status should return to “Ready” automatically.
