Are you seeing a black screen when attempting to go live? This is usually due to external software or another webpage capturing your cam feed. If anything else is using your cam or if you are using a cam splitter or an overlay, try turning those off first as they can cause interference. Otherwise, try these steps. 

• If your cam is external, unplug it and plug it into a new USB port
• Restart your device
• Try using a different browser (we recommend either Chrome or Firefox)
• If you're using OBS, try these troubleshooting steps: Camera connection issues
