Troubleshooting

No sound

First, make sure your device is not muted. If the volume is already turned up, check the video player’s own audio controls — these appear when you hover over the video.

If you are using headphones or an external speaker, verify that the correct audio output device is selected in your system settings.

Sound is echoing

This usually happens when the same event is open in more than one browser tab or window. Make sure the event page is open in only one tab.

If the echo persists, try reloading the page.

Video or audio keeps cutting out

This is typically caused by a slow or congested network connection. Try the following:

• Close other bandwidth-heavy applications (e.g. streaming services, large downloads, or video calls).
• If you are using a VPN, try disconnecting it or switching to a different network — some VPN configurations can interfere with video streaming.
• Switch from Wi-Fi to a wired connection if possible.

Browser crashes when the stream starts

This is rare, but it can happen. To resolve it:

1. Clear your browser’s cache and cookies.
2. Close and reopen the browser.
3. Navigate back to the event page.

If the issue continues, try using a different browser.

Presentation slides are not updating

Slides may occasionally take a moment to change during a live presentation. If they appear stuck, perform a hard reload:

• Windows: Ctrl + F5
• Mac: Cmd + R
• Linux: F5
