What's Wrong?

Description:
Persistent Authentication/Onboarding Loop on a Paid Max Plan (5 seats).

Details:
Since April 8th, I am unable to use the Claude CLI (claude-code) or the Web Interface. Despite a successful login, the system redirects indefinitely to /onboarding. Even after completing the onboarding steps, the session is not recognized, and the loop restarts.

Environment:

Plan: Claude Max (5 Seats)

Account: georg-schmidt-photography@web.de

Ticket-ID: 215473808533821 (Unresolved for 12 days)

What Should Happen?

Expected Behavior:
After login, the CLI/Web interface should recognize the existing active subscription and grant access to the workspace instead of triggering the onboarding flow repeatedly.

Error Messages/Logs

No specific error code in CLI, just a silent redirect to the browser for onboarding which never completes the authentication handshake. This appears to be a server-side database mapping issue for my specific account.

Steps to Reproduce

1. Open terminal and run claude (or go to claude.ai).
2. Complete the login process with a paid Max/Team account.
3. Observe the redirect to claude.ai/onboarding.
4. Complete the onboarding steps.
5. Instead of landing in the chat interface, the system redirects back to step 3 (infinite loop).

Additional Information

This auth-loop occurs on both the Web UI and the CLI. It prevents any usage of the tool for my business account. Please check internal Ticket-ID 215473808533821 for billing and account mapping details.
