Solving the Issue Where Claude Code on Desktop Fails to Resume Conversation Sessions ​

TLDR ​

  • When OAuth authentication expires, Claude Code triggers a 401 error, and the /login command fails to function correctly.
  • This is a known bug in Claude Desktop (Windows/macOS).
  • Temporary workaround: Manually close Claude Desktop and re-run the installer to restore the conversation session.

Symptoms and Causes ​

When you encounter this issue: When the OAuth authentication status of Claude Code expires due to inactivity, attempting to continue a conversation triggers an error.

Once authentication expires, the system returns the following error message:

text
API Error: 401 {"type":"error","error":{"type":"authentication_error","message":"OAuth token has expired. Please obtain a new token or refresh your existing token."},"request_id":"req_011CWWoXen3mpmsjy27LGmqn"} · Please run /login

However, when the user follows the prompt and enters the /login command, the following abnormal behavior occurs:

  • After entering the command for the first time, there is no visual feedback from the system.
  • After a short delay, the system reports Unknown slash command: login.

This issue prevents the current conversation session from continuing. It has been confirmed as a known bug in Claude Desktop. Related discussions can be found here:

Temporary Workaround ​

WARNING

The following is an unofficial temporary workaround. It is recommended to keep an eye on official updates and wait for a formal fix.

Before the official fix for the authentication reconnection mechanism is released, you can force the session to resume by following these steps:

  1. Manually close the Claude Desktop window (it is recommended to close it manually to avoid interference from residual processes).
  2. Re-run Claude Setup.exe.

After performing the steps above, the conversation session will immediately resume, without the need to log in again or start a new conversation.
