Thanks for reaching out! To help us get you up and running as quickly as possible, could you please share a bit more detail about your setup and what exactly happens when you try to start Roon? For example:
Are you running Roon Server and Roon app on the same PC, or is your server hosted on another device?
When you open the Roon app, do you see any error messages or just “Waiting for your Roon Server”?
Has anything in your setup changed recently (Windows update, antivirus/firewall, network equipment, etc.)?
How is your PC connected to the network — wired or Wi-Fi?
The more detail we have, the faster we can pinpoint what’s going on and suggest the right next steps.
