Check Bolt’s status
Before troubleshooting, check the Bolt status page for any active incidents. If Bolt is experiencing a known issue, check your project again after the issue resolves to see if that also resolves your problem.”Another project is already using this domain” error
If you see this error, it usually means the domain is still connected to a previous deployment on another hosting service. This happens when the domain wasn’t fully removed from that service’s domain management settings. If your domain was purchased through Netlify: Netlify usually lets you disconnect a domain from your project directly. If you’ve removed the domain from your Netlify projects and still see the error in Bolt, contact Netlify support so they can update the domain settings. If your domain was purchased through another provider:- Log in to the hosting service where the domain was previously connected.
- Go to the domain management settings.
- Check if your domain is still listed or connected to any old projects.
- Remove the domain if it’s still connected.
- Return to your Bolt dashboard and try connecting the domain again.
