fix: route GHEC Copilot proxy to copilot-api subdomain by Copilot · Pull Request #1331 · github/gh-aw-firewall

Copilot · 2026-03-17T04:29:47Z

On GHE Cloud data residency instances (*.ghe.com), the api-proxy was routing Copilot inference requests to api.<slug>.ghe.com, which returns 403/400 — the correct Copilot inference endpoint is copilot-api.<slug>.ghe.com (separate subdomain from the GitHub REST API).

Changes

containers/api-proxy/server.js — deriveCopilotApiTarget() now returns copilot-api.<slug>.ghe.com for all GHEC tenants instead of api.<slug>.ghe.com:

GITHUB_SERVER_URL=https://acme.ghe.com
Before: api.acme.ghe.com        ← GitHub REST API, returns 403 for Copilot
After:  copilot-api.acme.ghe.com ← Copilot inference/models/MCP, works correctly

src/cli.ts — extractGhecDomainsFromServerUrl() now auto-adds two additional domains to the firewall allowlist for GHEC instances:
- copilot-api.<slug>.ghe.com — inference, models, MCP
- copilot-telemetry-service.<slug>.ghe.com — telemetry
Previously only <slug>.ghe.com and api.<slug>.ghe.com were auto-added; all four are now included.
docs/enterprise-configuration.md — updated GHEC examples and domain breakdowns to reflect all 4 auto-added domains and the corrected routing target.
Tests updated in server.test.js and src/cli.test.ts accordingly.

Pull request overview

Fixes AWF’s Copilot api-proxy routing for GitHub Enterprise Cloud data residency tenants (*.ghe.com) by targeting the correct Copilot inference subdomain and ensuring the firewall allowlist auto-includes the required GHEC Copilot domains.

Changes:

Update deriveCopilotApiTarget() to use copilot-api.<slug>.ghe.com for GHEC tenants.
Expand GHEC auto-allowlisting to include copilot-api.* and copilot-telemetry-service.* domains (in addition to tenant + api.*).
Refresh docs and tests to reflect the corrected routing/allowlisting behavior.

`src/cli.ts`	Extends GHEC domain extraction so the firewall allowlist auto-includes Copilot inference + telemetry subdomains.
`src/cli.test.ts`	Updates tests to assert the new extracted/auto-added GHEC domains.
`docs/enterprise-configuration.md`	Updates examples and domain breakdowns for corrected GHEC routing and expanded auto-allowlisted domains.
