A GitHub account can only be connected to one Glitch account.

This error typically occurs if the GitHub account that you are trying to connect to is already linked to another Glitch account.   

If you see the error message when logging in, you can fix this by:

1. Closing the other Glitch account that is currently connected to the GitHub account.
2. Clearing your browser cache.
3. Then, login to your newer account and retry your action.

If you do not want to close the Glitch account that is currently connected to your GitHub account, you can send us a support request and we can re-assign the GitHub account to your other Glitch account for you.

If you see this error when trying to export your project to a GitHub repo, you can fix this by unlinking GitHub from your other account as follows:

1. Logging in to the other Glitch account that is currently connected to GitHub.
2. Opening the project editor for one of your projects.
3. Click Tools at the bottom of the page.
4. In the Tools menu, click Import / Export.
5. Click Revoke GitHub repo access
