I am unable to create any new Codex sessions.

Both chat creation and project/session creation are failing consistently with a timeout error.

Issue behavior

  • Creating a new chat → Timeout
  • Creating a new project/session → Timeout
  • Switching models does not resolve the issue
  • Existing sessions (if any) work normally, but cannot start new sessions

What I have tried

  • Restarting the app
  • Reinstalling the app
  • Logging out and logging back in
  • Switching models

None of the above steps resolved the issue.

Expected behavior

New chats and projects should be created successfully.

Actual behavior

All new session creation requests fail with a timeout, with no authentication or validation error shown.

Impact

I am currently unable to use Codex for any new tasks or sessions.

    Referring to the solution in #29416, the issue was temporarily resolved by disabling MCP.
