Troubleshooting / FAQ

Windows: “Windows protected your PC” (SmartScreen)

This is due to the unsigned build (for now). Click “More info” → “Run anyway”. The warning will go away once signing is in place.

Windows: the old icon stays after an update

This is Windows’ icon cache. Clear it (restart Explorer or the IconCache) and the icon will refresh.

macOS: “the app is damaged”

The app isn’t damaged — it’s not yet notarized. Right-click → Open, or allow it in System Settings → Privacy & Security. See Installation.

Kick: 401 error / moderation action refused

A permission is missing on your Kick app. Enable the required permissions (see Connect Kick) then reconnect in Streamly to regenerate the token.

YouTube: action not possible (title, moderation, chat)

YouTube requires an active or scheduled live. Check that a broadcast is running or planned, then try again. See Limitations.

An action fails after changing permissions

Apply the golden rule: disconnect then reconnect the platform to regenerate the token with the new permissions.

”Port 4747 already in use”

Another program (or an already-running instance of Streamly) is occupying port 4747. Close the app using it, or the duplicate instance, then restart Streamly.

Windows: the update fails

If the installer fails, it’s often because Streamly is still running. Fully close the app before launching the update.

An overlay doesn’t show / doesn’t update in OBS

• Check that Streamly is open (it serves the overlays).
• In OBS, right-click the source → Refresh cache of current page.
• Check that the Browser Source URL is the one copied from the app.
