Introduction: Quick fact and quick-start guide
Github Copilot not working with VPN? Here’s how to fix it. Copilot can struggle when your VPN causes traffic to route through blocked endpoints, modifies TLS/SSL handshakes, or introduces DNS leaks. Quick-start steps:
- Check if Copilot works without VPN to confirm the issue is VPN-related.
- Temporarily switch VPN servers to a nearby country to reduce latency and potential blocking.
- Ensure your IDE extension and Copilot are up to date.
- Verify DNS resolution and firewall rules aren’t blocking Copilot endpoints.
- If needed, adjust VPN protocol e.g., OpenVPN, WireGuard and split tunneling settings.

For quick access, you can also skim this practical checklist:
- Disable IPv6 on VPN if possible.
- Try different DNS providers 1.1.1.1 or 8.8.8.8.
- Use split tunneling to only route development traffic through VPN.
- Confirm that your IDE is allowed through any local firewall.
- Check Copilot status on status.github.com to rule out service outages.
1. Quick checks before you dive in
- Confirm Copilot status: Open your IDE and check if Copilot shows as available or if there’s a status message.
- VPN server selection: If you’re connected to a far-off location, latency can cause timeouts. Switch to a nearby server and retry.
- Update everything: Ensure your IDE, Copilot extension, and VPN client are the latest versions.
- Test without VPN: If Copilot works without the VPN, you’ll know you’re dealing with VPN-induced issues.
2. How VPNs affect Copilot and what to look for
- Endpoint blocking: Some VPNs route traffic through servers that GitHub Copilot or its authentication endpoints don’t like.
- TLS/SSL inspection: Some corporate VPNs inspect TLS traffic, which can break certificate validation for Copilot.
- DNS issues: VPN DNS can fail to resolve Copilot’s domains, causing timeouts.
- Split tunneling: If your VPN isn’t set to split-tunnel, all traffic goes through VPN and can slow or block Copilot.
- Rate limits and abuse protection: VPNs can trigger rate-limiting on GitHub services.
- Firewall rules: Local or ISP-level firewalls may block certain VPN endpoints used by Copilot.
3. Step-by-step fixes for common VPN-related problems
- Fix A: Use split tunneling for development traffic
- Enable split tunneling in your VPN client.
- Exclude your IDE executable and the Copilot endpoints from VPN routing if possible.
- Test Copilot after applying split tunneling.
- Fix B: Try a different VPN server or protocol
- Switch to a nearby server in your country or a neighboring country.
- If you’re using OpenVPN, try WireGuard or vice versa if available.
- Test Copilot after changing the server/protocol.
- Fix C: Disable IPv6
- Some VPNs don’t handle IPv6 well, causing DNS or routing issues.
- Disable IPv6 on your system or in the VPN settings if you can.
- Reconnect and test Copilot.
- Fix D: Adjust DNS settings
- Use a reliable DNS provider like Cloudflare 1.1.1.1 or Google DNS 8.8.8.8.
- Flush DNS cache after changes.
- Retry Copilot.
- Fix E: Check TLS/SSL inspection and certificates
- If you’re on a corporate VPN that inspects TLS, you may need to install a root certificate or disable TLS inspection for GitHub domains.
- Consult your IT policy or VPN admin before making changes.
- Fix F: Configure firewall rules or allowlists
- Ensure that GitHub Copilot endpoints vscode-copilot.githubusercontent.com, github.com, api.github.com are allowed through your firewall.
- Add exceptions for your IDE, Copilot, and VPN process if needed.
- Fix G: Clear caches and reset connections
- Clear IDE caches, sign out and back into Copilot, and reauthenticate.
- Restart the VPN client and your IDE.
- Fix H: Check authentication and tokens
- Ensure your GitHub account is properly authenticated in the IDE.
- Re-login to Copilot if the token expired or was revoked.
- Fix I: Check Copilot service status
- Visit status.github.com to see if Copilot or related services are experiencing outages.
- Fix J: Consider a local proxy for Copilot endpoints
- In some setups, a local proxy can help route Copilot traffic correctly when VPN blocks specific endpoints.
- This is advanced; follow official documentation and security guidelines.
4. Network and firewall considerations
- Corporate networks: IT policies may enforce strict VPN configurations that interfere with Copilot. Contact IT for exceptions or recommended settings.
- Personal firewalls: Windows Defender Firewall, macOS Firewall, or third-party tools can block Copilot endpoints. Add explicit allow rules.
- ISP throttling: Some ISPs throttle VPN traffic. Switching VPN servers or changing VPN providers may mitigate this.
- MTU settings: VPNs can have MTU-related fragmentation issues. If you see packet loss, adjust MTU to optimize performance.
5. Configuration tips for different environments
- Windows/macOS/Linux
- Ensure the environment variables for proxies http_proxy, https_proxy are properly set if you’re working behind a proxy.
- Enable or disable IPv6 based on what your VPN supports.
- Use a VPN server close to your location to minimize latency.
- IDE-specific tips
- Visual Studio Code: Update the Copilot extension to the latest version, reauthenticate, and check the Output panel for any Copilot specific errors.
- JetBrains IDEs: Verify the Copilot plugin settings, make sure the plugin has permission to access network, and inspect the IDE’s logs for connection errors.
- Mobile development environments
- If you’re on a mobile hotpot or tethered setup, ensure the laptop’s VPN configuration doesn’t conflict with mobile network settings.
- Consider using split tunneling more aggressively to keep development traffic on VPN while other traffic goes direct to the internet.
6. Best practices to prevent future issues
- Use a VPN with developer-friendly features: split tunneling, reliable DNS, and stable protocols.
- Keep Copilot enabled and authenticated; reauthenticate after major updates or password changes.
- Maintain a clean rule set on your firewall to avoid accidental blocks of Copilot endpoints.
- Regularly check the Copilot status page and community forums for known issues.
- Document your VPN settings for your development team so everyone has a baseline.
7. Extra troubleshooting tips and caveats
- Some VPNs aggressively block standard TLS fingerprints; if Copilot works on another network, this might be the root cause.
- If you see DNS leaks, you might be using a VPN that isn’t routing all DNS queries through the tunnel. Consider changing to a more robust DNS config or VPN that handles DNS properly.
- Logging: Turn on verbose logging in Copilot if available and capture any error codes. This helps when you search for help or contact support.
- Data privacy: When using VPNs for development, be mindful of what data is transmitted through VPN tunnels and ensure compliance with your company’s privacy policies.
