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
Note: To connect your GitHub Enterprise Server instance to GitHub.com, your proxy configuration must allow connectivity to
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. SOCKS5 and HTTPS proxies are not supported. For more information about using GitHub Actions with GitHub Enterprise Server, see "Getting started with GitHub Actions for GitHub Enterprise Server."
Configuring an outbound web proxy server
From an administrative account on GitHub Enterprise Server, in the upper-right corner of any page, click .
If you're not already on the "Site admin" page, in the upper-left corner, click Site admin.
In the left sidebar, click Management Console.
In the left sidebar, click Privacy.
Under HTTP Proxy Server, type the URL of your proxy server.
Optionally, under HTTP Proxy Exclusion, type any hosts that do not require proxy access, separating hosts with commas. To exclude all hosts in a domain from requiring proxy access, you can use
.as a wildcard prefix. For example:
Under the left sidebar, click Save settings.
Note: Saving settings in the Management Console restarts system services, which could result in user-visible downtime.
Wait for the configuration run to complete.
