Hi @KeizerSauze

I’m just a fellow Roon user.

Could help if you post a screenshot of the error message on the Arc screen inside the Roon (remote) settings.

Have you setup port forwarding in your routers settings.

ARC Port Forwarding

[KeizerSauze]

No, not yet, how can I do that? thanks!

Follow the link in @Menzies post above.

In order to get ARC working you need either a port forwarding setup or a Tailscale setup.

I’m not familiar with your ISP so there may be another wrinkle. If your ISP uses CG-NAT to supply you with a an Ip address, then Port Forwarding will not work. In this case, you will either have to get your ISP to give you a public ip address that supports port forwarding (and then you can set up port forwarding) or you will have to use Tailscale.

Thanks @Wade_Oram, i’l gonna figure how to do it on ly routeur.

Hi @KeizerSauze,

Since you’re using a MacOS RoonServer, a simpler option than port forwarding would be to install Tailscale. This will connect your Mac Mini to your phone automatically without port forwarding.

See here:

Tailscale Setup Instructions: MacOS RoonServer

MacOS Sequoia has tighter network security than previous MacOS versions. Make sure you’ve gone to System Settings → Privacy & Security → Local Network and toggled on local network access for RoonServer. This will make sure your local network Zones work with Roon.
