Overview
If the stream preview isn't loading in Multiview, there are several troubleshooting steps you can take. This issue is typically caused by viewing mode settings, browser state, stream status, or browser permissions. The sections below walk through each of these possibilities in order, starting with the easiest fixes first.

Switch Between WebRTC and HLS Viewing Modes
LIGR supports two viewing methods for monitoring streams, and switching between them is often the quickest way to get a preview loading again.
• WebRTC: Lower latency, better for real-time monitoring
• HLS: More stable, shows stream quality as your audience sees it
Try switching between these two modes to see if the preview loads. One mode may work better than the other depending on your network conditions or browser, so it's worth testing both before moving on to other troubleshooting steps.
Refresh the Browser Page
A simple browser refresh can resolve many preview loading issues. Refresh the Multiview page and wait for the stream tiles to reload before trying anything more involved.
Check That Stream Is Actually Active
Next, verify that the stream is actually live and not just scheduled, since the preview will not load in several common situations:
• The stream has been created but not started
• The stream is scheduled for a future time
• The stream has already ended
To confirm whether this is the cause, check the stream's status indicator to confirm it's active; a red indicator means the stream is live.

Verify Browser Permissions for Video Playback
If the stream is confirmed live and the preview still won't load, check that your browser has permission to play video content. Browser security settings may block video playback in some cases, so make sure your browser allows video playback for the LIGR Live site.
Additional Considerations
If the preview still doesn't load after trying all of the steps above, consider the following:
• Test with a different browser if the issue persists
• Use modern browsers (Chrome, Firefox, Edge) for best compatibility
• Keep your browser updated to the latest version
