Roon ARC only works with WIFI, not with mobile data network (France). I can connect with WIFI everywhere, Roon ARC is working fine, but if I'm using a mobile data network (Orange, France), no way to connect, Roon ARC tells me there's a Port Forwarding Issue and that I have to check the ARC settings on my Roon Server. When I'm back to wifi, it works immediately. The speed of the mobile data network is good.
Hello, I do not know what I have to change in the settings, Roon ARC works perfectly with wifi.
I have no error message in Roon server, only on my phone, in Roon ARC.
Please show a screenshot of Roon > Settings > Roon ARC.
When ARC is on the wifi, it does not need port forwarding on the router. Therefore, it can work even if port forwarding is broken. But when using mobile data, the port forwarding must work. (Unless you use the Tailscale solution for ARC, which does not rely on port forwarding, either)
I don’t know anything in port forwarding, and I don’t even know what it is. I don’t understand why there is a difference when my phone is connected to the internet with wifi (when I am not in my own house, Roon ARC works with wifi) and when it is connected with a mobile data network. Usually, I can always do the same things on my phone with both types of connection. Please help me!
If you want to use ARC with port forwarding, then you will have to learn some basics.
Because this is how the internet works. Your local network (wifi) and the Internet are not the same network. Therefore, the router sits between your local network and the Internet and translates between them. If it needs to allow access from the Internet to devices on the local network, it uses the technology called port forwarding to do this.
No, not really. You can do these same things if the router manages them by default, such as browsing the web.
Accessing your private servers is not such a thing, and this is good. Surely you don’t want everyone on the Internet to access your file server with your personal documents, either. It’s the same with the Roon server.
If you posted the screenshot that I asked you for, then we would already be a step farther.
Please also tell us what kind of computer you use for your Roon server. There may be simpler methods to get ARC working.
Good, thanks. OK, so according to this, the Roon server doesn’t think that there is an issue with the port forwarding. The router allowed the Roon server to configure it automatically for you, and the Roon server thinks that this worked.
Obviously, this makes it weird that ARC believes otherwise. Please also show us a screenshot of the ARC app where it complains about this.
Thanks. Did it ever work and just stopped, or did it do the same thing immediately as soon as you tried using it?
It’s clearly odd that the server and the app don’t agree. I think this is something that official support needs to take a look at. They may be able to get more information from the technical log files.
Rather than trying to figure out what’s wrong there with the port forwarding (which might not even work with your internet service provider), it is easier to use the alternative Tailscale method. It makes it seem to ARC on your phone as if it was connected to the local wifi. Therefore, the port forwarding is not necessary. Using Tailscale for ARC is fully supported by Roon Labs.
You just have to install Tailscale on Windows and the phone, and create a Tailscale account. You can read about the basics here:
