Hi! What’s not quite right with Roon?

· None of the above quite fits

None of the above quite fits

· App interface looks or behaves oddly

Tell us what's going on

Hello @Vancho_Kolev,

Welcome to the Roon Community — and thanks for reaching out.

At the moment, there isn’t enough information in the post for us to understand what’s going wrong. When you say “Roon doesn’t respond” or “doesn’t provide expected functionality”, this can mean several very different things.

Could you please clarify the following so we can help effectively:

1. Which Roon component is affected?

• Roon Server (where is it running: Windows, macOS, Nucleus, ROCK?)
• Roon Remote (phone, tablet, computer?)
• Roon ARC?

2. What exactly happens?

• Does the app fail to launch?
• Does it open but freeze / stop responding?
• Are buttons unresponsive, playback not starting, or something else?

3. Any error messages or screenshots?
   If you see an error message, please share the exact text or a screenshot.
4. When did this start happening?

• After an update?
• After a reboot or power outage?
• Or has it never worked correctly?

Once we have a bit more detail, we can point you in the right direction or start proper troubleshooting.

Looking forward to your reply, and happy holidays

Hello @Vadim,

I am using Roon for Windows PC ( HP Spectre !5 ) as a yearly subscriber.

All three apps ( Robin Server, Roon Roon bridge ) are unresponsive.

Roon stopped after the update.

Hope this information is helpful.

Merry Christmas and Happy New Year.

Hello @Vancho_Kolev,

Thank you for the clarification.

First, just to clear up one point: on Windows there is no longer a separate Roon Server / Roon Bridge installation. Everything is installed and managed as a single Roon package, so that part is expected behavior.

Based on the diagnostic logs we have, RoonServer itself is actually starting and running correctly on your system. For example, we can see the following entries:

This indicates that the server process is launching normally after the update.

When Roon appears “unresponsive” after an update on Windows, the most common cause is a stuck or orphaned Roon process left behind during the update, which prevents the UI from attaching correctly.

Please try the following steps:

1. Open Task Manager (Ctrl + Shift + Esc)
2. End all Roon-related processes, including:

• Roon
• RoonServer
• RAATServer

3. Once all Roon processes are fully stopped, restart your PC
4. After reboot, launch Roon again and wait 1–2 minutes for the UI to reconnect to the server

In most cases, this fully resolves post-update unresponsiveness on Windows.

If the issue persists after a clean reboot, please let us know:

• whether the Roon window opens at all
• whether it shows “Looking for your Roon Server” or freezes immediately

We’ll be happy to continue from there.
