claude-code - 💡(How to fix) Fix [BUG] OAuth session expires mid-session with 401, /login doesn't reliably refresh [1 comments, 2 participants]

Please run /login · API Error: 401 {"error":{"type":"authentication_error","message":"Invalid authentication credentials"}} 4. Running /login again sometimes succeeds temporarily but token expires again shortly after

TL;DR

The OAuth session expiration issue in Claude Code v2.1.126 can be temporarily mitigated by re-running the /login command, although a more permanent fix is needed to prevent frequent token expirations.

Guidance

• Investigate the authentication flow and token refresh mechanism to identify why the token expires prematurely, focusing on the OAuth session management in the Claude Code application.
• Verify if the issue is specific to the Claude Pro subscription or if it affects other users as well, to determine the scope of the problem.
• Check the Anthropic API documentation for any guidelines on handling token expirations and refreshing authentication sessions, as the issue might be related to the API's authentication mechanism.
• Consider implementing a token refresh mechanism that automatically renews the authentication token when it is close to expiring, to prevent interruptions in the user's session.

Example

No specific code example can be provided without more details on the implementation, but the solution might involve modifying the authentication logic to handle token refreshes more effectively.

Notes

The issue seems to be a regression, as it worked in a previous version, indicating that a change in the code or the Anthropic API might be the cause. Without more information on the previous working version, it's challenging to pinpoint the exact cause.

Recommendation

Apply workaround: Given the regression nature and the impact on the user experience, applying a workaround such as automatically refreshing the token upon expiration or implementing a more robust session management system seems necessary until a permanent fix can be developed and deployed.
