Cursor Doesn't Work with My VPN

VPN connectivity issues can affect Cursor's functionality, particularly with AI features and code indexing. Here's how to troubleshoot and resolve these problems.

Common VPN Issues​

  1. AI features not working
  2. Code indexing errors
  3. Connection timeouts
  4. Authentication failures
  5. GitHub integration problems

Troubleshooting Steps​

1. Check VPN Configuration​

  1. Ensure your VPN allows WebSocket connections
  2. Verify that required ports are not blocked
  3. Check if your VPN allows HTTPS traffic to Cursor's servers

2. Network Settings​

Tip: Try temporarily disabling VPN to isolate whether the issue is VPN-related. If Cursor works without VPN, you can configure split tunneling.

  1. Temporarily disable VPN to test connectivity
  2. If Cursor works without VPN, configure split tunneling:
    • Exclude Cursor from VPN routing
    • Allow direct connection for Cursor's domains

3. Corporate Networks​

For corporate VPN users:

  1. Contact your IT department
  2. Request allowlist for Cursor's domains
  3. Verify proxy settings if applicable

Best Practices​

1. Split Tunneling​

  • Configure VPN to only route necessary traffic
  • Keep Cursor traffic on direct connection when possible

2. Network Testing​

  • Use network tools to verify connectivity
  • Monitor connection logs for errors
  • Test different VPN servers if available

3. Configuration Management​

  • Document working VPN settings
  • Create separate VPN profiles if needed
  • Keep backup of working configurations

Alternative Solutions​

Warning: If VPN issues persist, consider these temporary workarounds while working with your IT team on a permanent solution.

  1. Use Cursor without AI features temporarily
  2. Consider dedicated development VPN profile
  3. Work with IT to create custom routing rules

Security Considerations​

Tip: Always maintain security best practices when configuring VPN exceptions or split tunneling.

Network Security​

  • Evaluate security implications of split tunneling
  • Maintain compliance with security policies
  • Monitor network traffic patterns
  • Regular security audits

Data Protection​

  • Ensure sensitive data remains protected
  • Follow company security guidelines
  • Document any VPN exceptions
  • Regular configuration reviews
