Description
I am repeatedly getting "Selected model is at capacity. Please try a different model." error.
The connection also drops with these errors:
- stream disconnected before completion: websocket closed by server before response.completed
- IO error: 远程主机强迫关闭了一个现有的连接。 (os error 10054)
This makes Codex completely unusable. It happens on Windows 10 build 19045. I am using model gpt-5.6-sol. It seems to be a server-side capacity issue, not my account or network.
Screenshot attached.

Research direction
Start by reproducing the reported model-capacity and websocket disconnect errors on Windows 10, using the issue's model and OS details. Trace whether the failure originates in the Codex client or the server-side capacity path; done means identifying an actionable cause and confirming the errors no longer make the client unusable.
