Describe the issue

Roon server (build 1583) runs on Windows NT 11 Pro (25H2), using port 50100 for ARC.

Describe your network setup

The Roon server (build 1583) runs on a Window 11 Pro (version 25H2).
It uses port 50100 for ARC.

The server (IP 192.168.2.212) is connected to Router A (Network 192.168.1.0, external IP 192.168.2.6). Port 50100 is forwarded to my ISP router (network 192.168.2.0 and IP 192.168.2.254  Internet). The ISP router forward port 50100 to the Internet.

Up till recently ARC worked okay. The ARC app on my FiFo M125 could connect to Roon server, play tracs and could download music files.

But lately, when I click the Again button (the twisted arrow) in Roon  setting  Roon ARC it takes a very long time (2-3 minutes) to give READY and the ARC app. Cannot connect. When I disable “offline mode” in settings an errlor wikndow pops up, saying “Roon server offline”. Repeatedly hitting the Retry button won’t
help.

How to solve this issue.

Can you please go to the Settings → Roon ARC and test connection and share the results with us here ?

Also, do you consider using VPN for the stable connection ?

Hi @Edwin_Slee,

Did you create a manual port forwarding rule in your router settings page? It looks like you’re relying on autoconfiguration with UPnP. It’s possible the router is simply having trouble negotiating an open port with the server when you refresh that page.

You can install Tailscale as an alternative to port forwarding using the instructions two posts above this one. This will open a separate network pathway between RoonServer and ARC - you can compare performance via Tailscale to port forwarding and see which is faster.

I made the “holes” see initial message. UPnP is of course switched off for security reasons.

I’ve disconnected Roon ARC from the server and reconnected, losing all my downloads!
Now Roon has online access.

Hey @Edwin_Slee,

Thanks for the update!

This is an unfortunate result of disconnecting and reconnecting to your server in Arc currently - you have my apologies about that!

Outside of that, it sounds like you’re now able to connect successfully, is that correct?

Thank you!

Indeed, ARC is okay now.

Hi @Edwin_Slee,

Thank you for the update. We are very glad to hear that the original issue is solved for now.

Regarding your point about files being missed during the reconnection—that is excellent feedback.

The best place for that observation is in our #feedback:feature-suggestions category.
