Network timeout and UPnP/NAT-PMP not found (ref#N6BIJ5)

Network Setup

· My only router was provided by my ISP

ARC Status

· ARC is *Not Ready*

Roon Error Code

· None of these are listed. It simply says "TIMEDOUT" or similar.

System or third-party *firewalls *or *antivirus software* can sometimes block RoonServer from reaching ARC.

·
Try adding RoonServer and its associated processes to the whitelist of any firewalls or antivirus software you have installed, including the Windows system firewall, if applicable.
[You can learn more about firewall exceptions with Roon here.](https://help.roonlabs.com/portal/en/kb/articles/firewall)

Has the status in Roon -> Settings -> ARC changed after adding exceptions in your firewalls and antivirus software for Roon?
ARC is still *Not Ready*

Don't give up yet.

· I'm stuck. I'd like to create a post to ask Roon Community for help.

You need to setup either Port Forwarding on your router or Tailscale on your Roon Server.

To setup port forwarding on your router, you can either set it up manually (forward TCP connections to the port shown on the Roon → Settings → Roon ARC page [From where you got the diagnostic text that you posted] - usually 55000 or thereabouts - to the ip address of your Roon Server shown on the smae settings page) or you can try enabling uPnP.

If you go the Tailscale route, what you see on the Roon → Settings → Roon ARC page will not change but it becomes irrelevant.

If neither of these options work, post an updated copy of the diagnostic text and we may then have more idea as to what is going on.

Note: If your ISP uses CG-NAT, then port forwarding will never work but Tailscale will work.

Hi @Victor_Manuel_Jarami,

If you’re using a MacOS or Windows RoonServer, we recommend installing Tailscale instead of setting up port forwarding with UPnP/NAT-PMP.

Tailscale is far simpler than port forwarding and will function even if your internet service provider uses carrier-grade network address translation (a common foe of ARC users).
