2626* A Linux or macOS host or container with outbound HTTPS to `api.anthropic.com`, to `claude.ai` and the download hosts it redirects to for the install step below, and to your git host for the clone; the [network requirements table](https://code.claude.com/docs/en/self-hosted-environments-deploy.md#network-requirements) has the full list. Windows isn't supported as a runner host; run the runner in a Linux container instead. Developer workstations aren't affected, since sessions start from claude.ai in a browser.
2727* A repository for the test session: a public one, or one this host can already clone by its HTTPS URL without being asked for credentials. An SSH key alone isn't enough, because the runner clones the repository's `https://` URL. To clone over SSH instead, see [Rewrite git URLs for private networks](https://code.claude.com/docs/en/self-hosted-environments-deploy.md#rewrite-git-urls-for-private-networks).
28* A clock synchronized to real time, for example with NTP. Authentication fails when the clock is more than five minutes off; see [Troubleshooting](https://code.claude.com/docs/en/self-hosted-environments-deploy.md#troubleshooting).
