❓ FAQ

A: This indicates that Claude Code does not detect environment variables. Check, please:

Are ANTHROPIC_AUTH_TOKEN and ANTHROPIC_BASE_URL correctly set

Is the environment variable value correct (the token starts with sk-)

If permanent configuration is used, whether the terminal has been restarted

Q: Why does the "offline" status appear?

A: Claude Code determines network status by connecting to Google. Showing "offline" does not affect normal use, it just means that you cannot connect to Google.

A: It may be a problem caused by the network environment. Solution:

Try using the proxy tool
