Why is Cursor AI not working?
Common causes and quick checks
First, check your internet connection and ensure Cursor's servers are operational. You can visit Cursor's status page or social media for outage reports. If there's an outage, wait and try again later.
Next, make sure you're running the latest version of Cursor. Updates often fix bugs and improve AI functionality. Also, verify that you're logged in and have available AI requests left in your plan. Free users have monthly limits; exceeding them disables AI features until the next cycle.
- Check internet connection and Cursor's status page.
- Update Cursor to the latest version.
- Ensure you're logged in and have remaining AI requests.
- Restart Cursor or your computer.
Settings and configuration issues
Incorrect settings can also cause AI to fail. For example, if you've entered an invalid API key or selected a model that's not available to you, requests may fail. Go to Settings > Models and verify your model selection and API key status.
Firewall or antivirus software might block Cursor's connections. Try temporarily disabling them to see if that resolves the issue. If you're behind a corporate network, proxy settings might need adjustment.
- Check Settings > Models for valid model and API key.
- Disable firewall/antivirus temporarily to test.
- Configure proxy settings if on a corporate network.
- Reset Cursor settings if misconfiguration is suspected.
Common mistakes
- Assuming it's a Cursor bug when it's a local network or account issue.
- Not checking usage limits; free plans have caps that can cause AI to stop.
- Ignoring the need to update Cursor regularly for bug fixes.
