Error Message

My network connection is working normally, and other websites and services work as expected. This issue happens repeatedly in VS Code. Sometimes Codex does not return a response for a long time and does not show any clear error message. Other extensions do not seem to have this issue. 5. Observe that Codex often stays on "Thinking" for a long time, sometimes around 5 minutes, without returning a response or showing a clear error message. Codex should start responding within a reasonable time, or show a clear timeout/error message if something goes wrong, instead of staying on the "Thinking" state indefinitely.

Codex IDE extension stays on "Thinking" for a long time

Over the past two days, the Codex IDE extension has often stayed on the "Thinking" state for a long time, even for very simple prompts. It can take around 5 minutes even for simple tasks.

What steps can reproduce the bug?

  1. Open VS Code.
  2. Open any repository.
  3. Open the Codex IDE extension panel.
  4. Send a simple prompt, for example:
    • "Please explain this small function."
    • "Check this file."
    • "Review this small change."
  5. Observe that Codex often stays on "Thinking" for a long time, sometimes around 5 minutes, without returning a response or showing a clear error message.

This does not happen every single time, but it has been happening repeatedly over the past two days.

What is the expected behavior?

Codex should start responding within a reasonable time, or show a clear timeout/error message if something goes wrong, instead of staying on the "Thinking" state indefinitely.
