HeyGen problems usually come from one of four places: your account session, browser setup, media input, or the video project itself. A quick diagnosis can save you from rebuilding a project that was working correctly.
Use this guide to work through common account, access, and video-creation issues. Start with the section that matches the error you see, then test the project again after each change.
When you can’t sign in to HeyGen
If HeyGen won’t let you sign in, first check that you’re using the same login method connected to your account. Switching between email login and a third-party sign-in option can lead you to a different account or make it appear that your projects are missing.
- Check the email address for spelling errors.
- Try the original sign-in method you used when creating the account.
- Open HeyGen in a private browser window to test for a stale session.
- Clear the site’s cookies and cached data if the login page loops or reloads.
- Temporarily disable browser extensions that affect scripts, pop-ups, or privacy settings.
A password reset email may also be delayed or filtered. Check your spam, promotions, and other filtered folders before requesting several resets. Repeated requests can make it harder to identify the newest message.
Account opens, but projects or features seem unavailable
When you can sign in but can’t see a project, confirm that you’re in the correct workspace or account. A project may have been created under another email address, especially if you use separate personal and work logins.
Refresh the dashboard, then sign out and back in. If the problem only happens in one browser, test another current browser. This helps separate an account issue from a local browser problem.
Some account functions can also depend on the plan or access arrangement attached to your account. Check the product or account details you received before assuming that a missing option is a technical fault. If you’re comparing HeyGen with Gamma AI alternatives, review each service’s current product details separately because similar tools can handle access and project limits differently.
HeyGen editor is slow, stuck, or not loading
A video editor that loads partially or freezes often needs a cleaner browser session. Close unused tabs, reload the page, and try a private window. If the editor works there, cached files or an extension is a likely cause.
Large uploads and busy projects can also take longer to open. Give the page time to finish loading before refreshing repeatedly. Multiple refreshes can interrupt an upload or leave the project in an uncertain state.
Try these checks:
- Use a stable internet connection and avoid switching networks during an upload.
- Update your browser to a current version.
- Disable extensions one at a time, especially ad blockers and script controls.
- Reduce the number of open editor tabs.
- Test a small new project to see whether the issue affects all projects or only one.
If a new project works while an older one does not, focus on the affected project’s media, text, or scene settings instead of changing your whole setup.
Avatar, voice, or script generation is not working
When a scene fails during creation, check the input before changing the entire project. Text with unusual punctuation, unsupported characters, excessive spacing, or very long sections can be harder to process. Shorten the script temporarily and test one scene.
If the shorter version works, add the content back in smaller sections until you find the part causing the failure. This takes less time than repeatedly submitting the complete script.
For voice-related problems, confirm that the selected voice is still available in the project and that the text field contains readable content. Preview a short sentence first. If the preview works, the issue may be limited to one scene or a longer script segment.
Keep your source script in a separate document while troubleshooting. That gives you a clean backup and makes it easier to compare changes.
Uploaded images or videos won’t process
Media problems often come from the file itself. Check that the upload completed and that the file opens normally on your device. If the file is very large, try a shorter clip or a smaller copy for testing.
Use a simple filename without unusual symbols, then upload the file again. Renaming the file won’t fix every issue, but it can remove a basic naming problem from the diagnosis.
Test one media file at a time. If one image or clip fails while another works, the project and browser are probably functioning, and the original file deserves closer attention. Re-exporting the media in a standard format from your editing software may help, provided you have the rights to use that content.
Video rendering is taking too long or stops before completion
First, check whether the problem affects one scene or the complete video. A single scene with a problematic script, asset, or setting can interrupt the full render.
Duplicate the project or save a separate copy before making major changes. Then remove one element from the suspected scene and try a shorter render. If that succeeds, restore elements one by one.
Avoid closing the browser during an active process unless the interface clearly shows that the job has stopped. If the page becomes unresponsive, record the last visible status and retry after reopening the project. Repeating the same failed render without changing anything rarely provides useful information.
Audio, subtitles, or timing look wrong
Timing issues are easier to isolate when you review the video scene by scene. Listen for pauses, cutoffs, or pronunciation problems and compare them with the script shown in the editor.
Shorten sentences that run together and add punctuation where a natural pause is needed. Break long text into separate scenes when the pacing becomes difficult to control. For subtitles, check spelling, line breaks, and whether the text matches the final voice track.
If the audio and visuals drift apart after editing, review any scene changes, replaced media, or altered script sections. Make a small correction, preview that section, and only then export the complete video again.
Export fails or the downloaded file is missing
Confirm that the video finished processing before looking for the download option. If the export appears complete but the file is missing, check your browser’s download history and the default downloads folder.
Try exporting a shorter version to separate a project-size problem from an account or browser issue. Also check available storage on your device. A successful online render can still fail to save locally when there is not enough space.
If the export fails repeatedly, keep the project copy and note the exact scene, format, and stage where the failure occurs. That information is more useful than simply reporting that the video did not download.
When to check the product details before troubleshooting
If your issue involves account access, plan entitlements, or the way your HeyGen access was supplied, review the listing you used for the purchase. The relevant destination is HeyGen AI Video Generator AI Videos on Keys-Shop. Use the product page as the reference for the specific offering instead of assuming that another AI video service has identical terms.
Readers comparing tools may also search for Gamma AI features or Gamma AI how to buy in India. Those are separate research questions from fixing a HeyGen project, so verify the exact product name and access details before making a purchase decision.
FAQ
Should I clear my browser data if HeyGen is not loading?
Yes, clearing cached site data can help with login loops, blank editor screens, and outdated page files. Test a private window first. If the private window works, clear data for the affected site and sign in again.
How can I tell whether the problem is my account or my browser?
Try a private window, another current browser, or another device on the same account. If the issue follows the account, check workspace and access details. If it stays in one browser, focus on cookies, extensions, and cached files.
Is Keys-Shop safe for Gamma AI?
The supplied Keys-Shop context identifies product pages for digital tools, including the HeyGen AI Video Generator listing. Review the exact product page details before buying and make sure the product name matches the service you intend to use. Do not assume that a page for one AI platform provides access to another.
What should I do before contacting support?
Record the error message, browser, device, affected project, and the step that failed. Note whether a private window or a smaller test project worked. A clear description helps distinguish an account issue from a specific media or scene problem.
