¿Quién puede utilizar esta característica?

GitHub Copilot se pueden administrar a través de cuentas personales con GitHub Copilot Individual, a través de cuentas de la organización o empresa con GitHub Copilot Business, o a través de cuentas empresariales con GitHub Copilot Enterprise.

GitHub Copilot es gratis para los alumnos comprobados, profesores y los mantenedores de proyectos populares de código abierto. Para más información, consulta "Acerca de la facturación de GitHub Copilot".

If you're working on company equipment and connecting to a corporate network, you may be connecting to the Internet via a VPN or an HTTP proxy server. In some cases, these types of network setups may prevent GitHub Copilot from connecting to GitHub's server. For more information about the options for setting up proxies with GitHub Copilot, see "Configuring network settings for GitHub Copilot."

This article provides guidance for common issues related to HTTP proxies and custom certificates. If you use a firewall, this may also interfere with GitHub Copilot's connection. For more information, see "Troubleshooting firewall settings for GitHub Copilot."

Diagnosing network issues

If you're troubleshooting network issues, it may help to make curl requests to test your connection. If you add the --verbose flag, these requests give you more information to diagnose the issue, or to share with your company's IT department or GitHub Support. You can contact GitHub Support through the GitHub Support portal.

To check if you can access at least some of GitHub's endpoints from your environment, you can run the following command from the command line.

Shell
curl --verbose https://copilot-proxy.githubusercontent.com/_ping

If you're able to connect, you should receive an HTTP 200 response.

If you know you are connecting via an HTTP proxy, you can check if the request succeeds when made via the proxy. In the following example, replace YOUR-PROXY-URL:PORT with the details for your proxy.

Shell
curl --verbose -x http://YOUR-PROXY-URL:PORT -i -L https://copilot-proxy.githubusercontent.com/_ping

If you receive an error related to "revocation for the certificate," you can try the request again with the --insecure flag. If the request only succeeds when the --insecure flag is added, this may indicate that GitHub Copilot will only connect successfully if you ignore certificate errors. For more information, see "Troubleshooting certificate-related errors."

If you're specifically having difficulty with Copilot Chat in your editor, run the above curl commands but use https://api.githubcopilot.com/_ping instead of https://copilot-proxy.githubusercontent.com/_ping.

If you're unable to connect and the curl requests don't help to identify the error, it may help to collect detailed diagnostic logs in your editor. If you're working with your company's IT department or GitHub Support, sharing these diagnostics may help to resolve the error. Enabling debug logging in your editor will help you to share more specific information. For more information, see "Viewing logs for GitHub Copilot in your environment."

Troubleshooting proxy errors

If there is a problem with your proxy setup, you may see the following error: GitHub Copilot could not connect to server. Extension activation failed: "read ETIMEDOUT" or "read ECONNRESET". This error can be caused by a range of network issues.

If you know you are connecting via a proxy, make sure the proxy is configured correctly in your environment. For more information, see "Configuring network settings for GitHub Copilot."

Note

If you are an employee of a company with a proxy server, your company must also configure proxy settings for Copilot at the company level. See "Configuring your proxy server or firewall for Copilot."

GitHub Copilot uses custom code to connect to proxies. This means a proxy setup supported by your editor is not necessarily supported by GitHub Copilot. Some common causes for errors related to proxies are:

  • If your proxy's URL starts https://, it is not currently supported by GitHub Copilot.
  • You may need to authenticate to the proxy. GitHub Copilot supports basic authentication or authentication with Kerberos. If you are using Kerberos, ensure you have a valid ticket for the proxy service and that you are using the correct service principal name for the service. For more information, see "Configuring network settings for GitHub Copilot."
  • GitHub Copilot may reject custom certificates. For more information, see "Troubleshooting certificate-related errors."

Depending on your proxy setup, you may encounter errors like "certificate signature failure," "custom certificate," or "unable to verify the first certificate." These errors are usually caused by a corporate proxy setup that uses custom certificates to intercept and inspect secure connections.

Some possible ways to resolve certificate-related errors are:

  • Configure a different proxy that does not intercept secure connections.

  • If you are using a corporate proxy, contact your IT department to see if they can configure the proxy to not intercept secure connections.

  • Ensure the custom certificates are properly installed in your operating system's trust store. For more information, see "Configuring network settings for GitHub Copilot." If the certificates are installed on your machine but GitHub Copilot isn't detecting them, it may help you to know the mechanisms that GitHub Copilot uses to find certificates.

    • On Windows, Copilot uses the win-ca package.
    • On macOS, Copilot uses the mac-ca package.
    • On Linux, Copilot checks the standard OpenSSL files /etc/ssl/certs/ca-certificates.crt and /etc/ssl/certs/ca-bundle.crt.
  • Configure GitHub Copilot to ignore certificate errors. In your proxy settings, you can deselect Proxy Strict SSL in Visual Studio Code, or select Accept non-trusted certificates automatically in a JetBrains IDE. For more information, see "Configuring network settings for GitHub Copilot."

    Warning

    Ignoring certificate errors can cause security issues and is not recommended.

If you or your organization use security software that monitors secure web traffic and you receive an "unable to verify the first certificate" error, you may need to configure an exception for your IDE and/or the copilot extension.

For more information about how to configure an exception, refer to your security software vendor.
