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?
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
· Something else
Don't give up yet.
· I'd like to try out Tailscale instead of port forwarding.
Please visit the link below for instructions to set up Tailscale.
· I'm having trouble with Tailscale and need to ask a few more questions.
Describe the issue
arc is still not ready
Describe your network setup
ISP: Verizon Fios
Router Make/Model: Arcadyan G3100 (Verizon Fios Router)
Modem: Integrated into the G3100 (no separate modem)
UPnP: Enabled (or disabled if using Tailscale)
Network Topology:
G3100 router connected directly to Verizon’s ONT (fiber terminal).
Roon Server is connected via Ethernet to G3100
Other smart devices (phones, tablets) on the same local Wi-Fi network (Sorrento 6G SSID).
Roon Server Details:
OS: macOS // RoonOS app
ARC: Installed and active on iOS with Tailscale
Roon Server IP address: (e.g., 192.168.1.123)
ARC device IP (if needed): 100.105.28.11
Additional Notes:
Port forwarding was not used; instead, using Tailscale to create a secure connection between mobile and Roon Server.
Roon ARC is able to reach the server successfully via Tailscale when outside the local network.
