Cannot correct a mistyped GitHub Enterprise domain during setup

[teaguestockwell]

Short summary

GitHub Enterprise sign-in remains locked to a mistyped domain with no way to edit or reset it.

Affected version or release

v1.1.12 (commit 5265222)

Installation context

Local GitHub Copilot desktop app installation on Windows x86-64. The problem occurs during initial setup, before authentication or repository access.

What happened?

During initial setup, I selected GitHub Enterprise sign-in and mistyped the domain as ghe.microsoft.com instead of microsoft.ghe.com.

After continuing to the device-code screen, I could not return to the domain-entry step or change the enterprise domain. The only available paths were to perform a health check or return to the device-code screen.

Quitting and reopening the app did not make the domain editable or restart the sign-in configuration, leaving setup blocked.

Steps to reproduce

1. Install and open the GitHub Copilot app.
2. Begin the initial sign-in experience.
3. Select GitHub Enterprise.
4. Enter an incorrect domain, such as ghe.microsoft.com.
5. Continue to the device-code screen.
6. Attempt to return to the domain-entry step and correct the domain.
7. Quit and reopen the app.
8. Observe that there is still no way to enter the correct domain.

Expected behavior

The sign-in flow should provide a way to go back and edit or clear the GitHub Enterprise domain.

Restarting the app before authentication is completed should also allow the sign-in configuration to be restarted.

Additional context

• Operating system: Windows x86-64
• GitHub Copilot app: 1.1.12
• App commit: 5265222
• Bundled Copilot CLI: 1.0.80
• Bundled GitHub CLI: 2.96.0

The exported health check confirms that authentication was not saved:

"auth": {
  "host": null,
  "login": null,
  "message": "No saved GitHub authentication found."
}

The application log identifies the affected build:

GitHub Copilot app started ... version=1.1.12 commit=5265222 platform=windows arch=x86_64

I have a complete diagnostics archive and can provide it privately if needed. I have not attached it publicly because it contains local usernames, filesystem paths, ports, and environment details.
