Description of Issue

I tried to activate Roon ARC, but I will get a time out:


“connectivity”: {“status”:“NetworkError”,“status_code”:504,“error”:“error: Error: ETIMEDOUT, response code: undefined, body: undefined connected? undefined”},

“external_ip”: {“actual_external_ip”:“84.135.XXX.XXX”,“router_external_ip”:“84.135.XXX.XXX”},

“natpmp_autoconfig”: {“status”:“NotFound”},

“upnp_autoconfig”: {“server_ip”:“”,“found_upnp”:true}


Thx XXX.XXX is replacing the actual values for not exposing my IP address here in the forum. Of course there is a real value existing.

The fritzbox is configured like this:

Hey @Cosmic_Encounter,

My apologies for the delay in response! Please give this thread a read and let me know if it helps:

Of course I had read this 2 threads before. As you can see with my screen shots, everything is made like this. In addition I have changed the name of the web connection to the name of the Roon kernel. But this didn’t help, too. I assume that the connection ist not accessible from outside. I do not now if this has something to do with my provider Telekom or with something else. Please help.

Hey @Cosmic_Encounter,

Can you confirm that your ISP Telekom has assigned you a static IPv4 address? You may need to reach out to them to confirm this.

I’ll be on standby for your reply :+1:
