Problem
Third-party chat widgets fail and leave stale messages visible on the broadcast overlay.
Solution
Root Cause / Diagnostic:
Third-party browser source widgets rely on persistent WebSocket connections that can drop without triggering automatic re-authentication during multi-hour broadcasts. When connection loss occurs, the overlay freezes the last received message permanently on screen, cluttering the broadcast.
Actionable Fix:
1. Enable Automatic Browser Source Refreshing: In OBS Studio / vMix browser source properties, check "Shutdown source when not visible" and "Refresh browser when scene becomes active".
2. Program a Dedicated Cache-Refresh Hotkey: Bind a dedicated hotkey on your control deck to execute "Refresh cache of current page" across all active browser sources in OBS.
3. Implement Visual Connection Heartbeats: Add a small dynamic heartbeat icon or blinking CSS timestamp to the widget overlay so the technical director can verify real-time data flow at a glance.
Pro Tip:
Run chat overlays through a local server or lightweight standalone app (like Chatty or locally hosted CSS/HTML scripts) rather than external cloud widgets to eliminate external server disconnects.
