Description

What version of the Codex App are you using (From “About Codex” dialog)?

26.908.70816

What subscription do you have?

Pro Lite

What platform is your computer?

Microsoft Windows NT 10.0.26200.0 x64

What issue are you seeing?

Codex frequently fails with:

"Selected model is at capacity. Please try a different model."

OpenAI Status shows no active incident, and codex doctor reports healthy auth, HTTP connectivity, and a successful WebSocket HTTP 101 handshake.

What steps can reproduce the bug?

Feedback ID: 01a0a78c-2547-7231-a3bb-5d200048d632

What is the expected behavior?

Codex should process the request normally when the model is available, or show the actual underlying error instead of a misleading capacity error.

Additional information

Please inspect the backend request associated with the Feedback ID to determine why this environment repeatedly receives capacity errors despite healthy connectivity.

Research direction

Start with the reported Feedback ID 01a0a78c-2547-7231-a3bb-5d200048d632 and the request path associated with the capacity error; compare it with the healthy codex doctor authentication, HTTP, and WebSocket results. Done means identifying why this Windows Pro Lite environment receives repeated capacity errors and ensuring the user sees the underlying error when capacity is not the cause.
