Cannot Access Roon ARC with or without Tailscale (ref#H3E96V)

Support
1

Network Setup

· I use a single personal router not 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'm stuck. I'd like to create a post to ask Roon Community for help.

Describe the issue

I can't access to Roon ARC, I have the same error message with or without Tailscale

Describe your network setup

My ISP is Free, my router is a Synology 2600ac, Roon is on a Mac Mini (15.4.1)

Note that the error message in Roon > Settings > Roon ARC will still be displayed if you enable Tailscale. However, in this case it means nothing and you can ignore it.

If you enable Tailscale, ARC should work if you are outside of your home network. If it does, everything is fine.

Hi,

I’m outside home, same error.

Hello @KeizerSauze,

Thank you for reaching out to Roon Support!

Could you kindly confirm when your phone — the one with ARC installed — was last connected to the same local network as your Roon Server?

This information will help us determine whether ARC had the opportunity to sync properly with your Core.

Looking forward to your reply!

I’m back home, connected to my LAN.

Thanks

Hello @KeizerSauze,

Thank you for reaching out.

It appears that ARC is currently unable to authenticate your device. To resolve this, please try the following steps:

  1. Open ARC and go to Settings
  2. Scroll down to the bottom and select Disconnect from <server name>
  3. After disconnecting, tap on “<” near your account and proceed with the initial login process again

Let us know if this helps or if you encounter any issues during the process — we’ll be happy to assist further.
