By john If you use HeyGen for creating AI avatar videos, you may have already run into avatar lips not syncing with the audio. It’s a common enough complaint that there are usually clear, practical steps you can take before assuming anything is permanently broken.
Understanding whether the issue sits on your device or on HeyGen’s servers RAFFIPLAY is the fastest way to know which fixes are worth trying first.
Possible Causes
- Cached data or cookies stored locally can conflict with how HeyGen loads or processes new requests.
- Conflicts with browser extensions or other background software can interfere with how HeyGen runs.
- A temporary outage or maintenance window on HeyGen’s end can affect requests without much warning.
- High server demand during busy hours can slow down or interrupt processing related to creating AI avatar videos.
- An outdated app or browser version can lose compatibility with recent changes to how HeyGen handles requests.
Initial Troubleshooting Steps
- Log out of HeyGen completely and log back in to refresh your session.
- Wait a few minutes and try creating AI avatar videos again, since temporary server congestion often resolves on its own.
- Refresh the page or fully restart HeyGen before trying the same action again.
Advanced Steps
- Break a large or complex request into smaller pieces before running it through HeyGen again.
- Test creating AI avatar videos again during a quieter time of day to see if server load is a factor.
- Try creating AI avatar videos on a different device or browser to see if the issue is specific to your original setup.
- Reinstall HeyGen entirely if the problem persists, since this clears out any corrupted local data.
- Update HeyGen to the latest available version through your app store or browser extension page.
Security and Data Warning
If you’re troubleshooting creating AI avatar videos on a shared or public device, make sure to log out of HeyGen fully once you’re done, and avoid saving your password on that device.

Conclusion
