What issue are you seeing?

In Visual Studio Code, when enabling "Run Codex In Windows Subsystem For Linux" (WSL) I cannot sign into my ChatGPT account (using Google account) to authenticate. It gives the error:
Token exchange failed: error sending request for url (https://auth.openai.com/oauth/token)

What steps can reproduce the bug?

  • Turn on "Run Codex In Windows Subsystem For Linux" in extension settings
  • Try to sign in
  • Use Google account as sign in
  • FAIL

What is the expected behavior?

Expect to sign in and authenticate as it does when WSL is not enabled.
