· 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? I don't have any system or third-party firewalls or antivirus software.
Have you successfully located and enabled the UPnP or NAT-PMP settings in your router's web UI?
· I've turned UPnP/ NAT-PMP on and ARC won't connect
Select the Diagnostic Keyword or Text String

Don't give up yet.

Can you please test Roon ARC readiness from the Roon’s → Roon ARC setting ? After that please share a screenshot or text with us which should look like this:
This will help us to understand what could be a blocker there.
The ISP you listed (Verizon FIOS) usually doesn’t block port forwarding at the provider level. It’s likely we can resolve this problem with a few settings changes in your router if you’re still having trouble.
Please open the router settings page - this is often an app for Verizon. Sometimes, it’s n IP address listed on the physical router itself that you can enter into a browser URL bar.
There should be a tab labelled “port forwarding.” Please create a manual port forwarding rule, TCP protocol, pointing to the port number and IP address that you see listed in the Roon Settings → ARC page.
Let us know if this helps. Here’s an article with more precise instructions, in case that’s helpful:
In the event that port forwarding still fails, you can instead install Tailscale alongside ARC on your phone and use the built-in Tailscale interface in your Nucleus One to reach ARC. This is an alternative to port forwarding. Here’s an article explaining further:
This thread will close without a response after a few more days, so please let us know if we can assist further in the meantime. Thank you!
