[Bugs] can't add my enterprise account: https://github.

can't add my enterprise account: https://github.vodafone.com/
Is my company blocking github copilot app or is there some errors. I got the following message:

Device code request failed (404 Not Found): {"error":"Not Found"}

---
| Field | Value |
| --- | --- |
| App version | 1.0.12 |

Start by reproducing enterprise account sign-in from the /workflows path on macOS with app version 1.0.12, focusing on the device code request that returns 404 for github.vodafone.com. Done means the enterprise account can be added successfully without the Device code request failed error; the issue does not identify a source file or test.
