Claude Redirected Back to Login Page? Fix Cookies, SSO, and Browser Session Issues
If Claude keeps redirecting you back to the login page, test incognito first. If it works there, clear site data for claude.ai, disable extensions, and turn off VPN/proxy. If it fails across devices and networks, it’s likely an SSO/workspace access issue or a platform-side auth incident.
Step-by-Step Fix
1) Reproduce once and capture the redirect URL
- Note the exact URL you land on after login
- Note timestamp and browser
This helps diagnose SSO/workspace loops.
2) Do the incognito test
- Open an incognito/private window
- Visit Claude and log in
If it works, it’s local browser state.
3) Clear only Claude site data
In your normal browser:
- clear site data for
claude.ai - close all Claude tabs
- reopen and sign in
4) Disable extensions and strict cookie settings
Temporarily disable:
- ad blockers
- privacy/script blockers
- cookie auto-delete tools
Also ensure cookies are allowed for Claude.
5) Turn off VPN/proxy and switch network
- disable VPN/proxy
- try a phone hotspot
If hotspot works, your network is filtering auth.
6) Check workspace/SSO context
If you’re on a team/workspace:
- confirm you’re logging into the correct email
- confirm you have access to the workspace
A common “login loop” is being authenticated but denied workspace access.
Common Root Causes
- stale cookies/session
- extensions blocking auth callbacks
- strict cookie policies
- VPN/proxy/network filtering
- SSO/workspace mismatch
- platform-side auth incident
Prevention Tips
- keep one clean browser profile for Claude
- avoid rapid retries when a loop starts
- test hotspot + incognito before changing account settings

Common Mistakes to Avoid
- Troubleshooting the wrong account or workspace.

What to Gather Before Contacting Support
- Capture the exact error message and the time it happened.
- Record whether the issue happens on another browser, device, or network.
- Note which account, workspace, or subscription plan is affected.
