When I send a simple prompt (for example, 123123123123123), Codex repeatedly tries to reconnect and then fails.
I see the following messages in sequence:

Reconnecting... 2/5
stream disconnected before completion: URL error: Proxy URL scheme not supported
Reconnecting... 3/5
stream disconnected before completion: URL error: Proxy URL scheme not supported
Reconnecting... 4/5
stream disconnected before completion: URL error: Proxy URL scheme not supported
Reconnecting... 5/5
stream disconnected before completion: URL error: Proxy URL scheme not supported
This happens even with very short/non-complex prompts.

What steps can reproduce the bug?

What steps can reproduce the bug?

Open Codex desktop app on Windows 11.
Start a new thread/session.
Enter a simple prompt such as 123123123123123.
Send the prompt.
Observe repeated reconnect attempts and final failure with Proxy URL scheme not supported.
I can reproduce this consistently.

What is the expected behavior?

The prompt should be processed normally without repeated reconnect attempts, and the response stream should complete successfully.

Additional information

The behavior suggests a proxy configuration/parsing issue.
It may be related to system or environment proxy settings (scheme format unsupported by the app/runtime).
If helpful, I can provide sanitized proxy-related environment variable values and more logs.
