Failed to fetch models after changing key; connectivity speed test failed

Cause

Section titled “Cause”

When using cc-switch 3.16.5 to manage Codex on Windows, changing the key after switching internal networks can prevent the model list from loading and cause the connectivity speed test to fail. Restarting cc-switch restored both functions.

The Issue provided no logs or further reproduction details, so the exact root cause is unknown. The Issue was closed because no new information was provided for a long time, not because a fix was confirmed. The maintainer said 4.0 substantially refactored the related functionality and recommended updating to the latest version and retrying.

Fix

Section titled “Fix”

  1. After switching internal networks and encountering the problem, restart cc-switch. The reporter confirmed that model list retrieval and the connectivity speed test both recovered after the restart.

  2. Update to the latest version and test again. This recommendation came from the maintainer, but the Issue contains no user confirmation that the update resolved the problem.

  3. If the problem persists in the latest version, provide the CC Switch version, operating system, complete reproduction steps, and relevant logs or screenshots, then reopen the Issue.
