Troubleshooting firewall settings for GitHub Copilot

Troubleshooting help for firewall-related errors.

Who can use this feature?

GitHub Copilot can be managed through personal accounts with GitHub Copilot Individual or through organization accounts with GitHub Copilot Business.

GitHub Copilot is free to use for verified students, teachers, and maintainers of popular open source projects. If you are not a student, teacher, or maintainer of a popular open source project, you can try GitHub Copilot for free with a one-time 30-day trial. After the free trial, you will need a paid subscription for continued use. For more information, see "About billing for GitHub Copilot."

If you or your organization employs security measures like a firewall or proxy server, it may be beneficial to include certain domain URLs in an "allowlist" and open specific ports and protocols. Doing so will enhance your installation and usage of Copilot for an optimal experience.

URLs to add to an allowlist

Due to Copilot's interaction with a remote machine learning model and its update checking functionality, it is recommended to include the following domain URLs in the allowlist, marking them as trusted either in the user interface or within your deployment scripts.

Domain and/or URLPurpose
https://github.com/login/*Authentication
https://api.github.com/userUser Management
https://api.github.com/copilot_internal/*User Management
https://copilot-telemetry.githubusercontent.com/telemetryTelemetry
https://default.exp-tas.com/Telemetry
https://copilot-proxy.githubusercontent.com/API service for Copilot suggestions
https://origin-tracker.githubusercontent.comAPI service for Copilot suggestions
https://*.githubcopilot.comAPI service for Copilot suggestions

Additional domains and URLs may require allowlisting, depending on your organization's security policies and the editors in use. For more information about specific editors, see "Further reading."

Note: On February 1, 2024, the Copilot Chat API endpoints that were routed through https://copilot-proxy.githubusercontent.com were deprecated. Instead, these requests go through https://api.githubcopilot.com/. Please ensure you are using the most recent version of the Copilot extension and ensure your firewall and network settings allow communication to https://api.githubcopilot.com.
