Hi @dhncc1,

Welcome to the Roon community! I’m sorry you’re running into trouble, but we’re happy to help. As @Carl mentioned, we need a bit more information to troubleshoot properly, but it looks like you’re dealing with a port forwarding issue for ARC. The error you posted means that Roon wasn’t able to set up port forwarding automatically, so here are your options:

1. The easiest solution is to skip port forwarding altogether and use Tailscale to connect ARC to your server. You can follow this guide to set it up.
2. If you prefer, you can manually configure port forwarding on your router instead. This article walks you through the process.

If you have any questions after reviewing the articles, let us know—we’re happy to help!
