Backend Connection Issue in GitHub Codespaces Environment

Body

Issue Summary:
In our development environment, specifically using GitHub Codespaces, the frontend operates as expected when accessed through a URL ending in github.dev (replacing the traditional localhost:5174). Direct access to the backend, also via a github.dev URL (replacing localhost:3000), encounters no issues when accessed independently. However, attempts to connect to the backend from the frontend result in connection failure. This issue does not occur when the same setup is tested on a Mac environment with a traditional localhost setup, where the connection is established without any issues.

Environment:

• Backend: NestJS
• Frontend: Vite
• Node.js Version: 20
• Development Environment: GitHub Codespaces

Steps to Reproduce:

1. Start the backend on a github.dev URL (replacing the traditional localhost:3000).
2. Launch the frontend on a different github.dev URL (replacing the traditional localhost:5174).
3. Attempt to make API calls from the frontend to the backend.
4. The connection to the backend fails.

Expected Result:
Requests from the frontend should successfully reach the backend and be processed accordingly, despite the development environment being hosted on GitHub Codespaces.

Actual Result:
Connection attempts from the frontend to the backend fail, resulting in errors, suggesting a potential issue with the GitHub Codespaces networking or configuration setup.

Attempted Solutions:

• Restarting both backend and frontend services within Codespaces
• Verifying the version of Node.js
• Testing the setup in a Mac/WSL environment with traditional localhost (where it works without issues)

I'm having the same issue. On my end, it seems that the frontend requests are being redirected to a GitHub login page. I'm not sure how to resolve this. Did you make any progress with this @tictaqqn?

Try sending the X-GitHub-Token request header from your frontend. Docs
