    Configuring an outbound web proxy server

    A proxy server provides an additional level of security for your GitHub Enterprise Server instance.

    About proxies with GitHub Enterprise Server

    When a proxy server is enabled for your GitHub Enterprise Server instance, outbound messages sent by GitHub Enterprise Server are first sent through the proxy server, unless the destination host is added as an HTTP proxy exclusion. Types of outbound messages include outgoing webhooks, uploading bundles, and fetching legacy avatars. The proxy server's URL is the protocol, domain or IP address, plus the port number, for example http://127.0.0.1:8123.

    Note: To connect your GitHub Enterprise Server instance to GitHub.com, your proxy configuration must allow connectivity to github.com and api.github.com. For more information, see "Connecting your enterprise account to GitHub.com."

    If GitHub Actions is enabled for your enterprise, only HTTP proxies are supported. SOCK5 and HTTPS proxies and Polipo are not supported. For more information about using GitHub Actions with GitHub Enterprise Server, see "Getting started with GitHub Actions for GitHub Enterprise Server."
