Here's the info from the Claude team:
The incident affecting claude.ai is still ongoing and hasn't been fully resolved yet. While a fix was implemented, the incident remains in "monitoring" status as of the latest update at 10:55 UTC, which states "We are continuing to monitor for any further issues."
This active incident is directly causing the OAuth authentication errors you're experiencing with Claude Code. Even though the status page shows a fix was deployed, the incident hasn't been marked as resolved, which explains why you're still unable to authenticate.
Since this is an ongoing service issue, the best approach is to wait for the incident to be fully resolved. You can monitor the status at https://stspg.io/f73w8hlj5tvs for real-time updates.
Once the incident is completely resolved, if you're still experiencing authentication issues, you can try these steps:
Run /logout to sign out completely
Close Claude Code entirely
Run claude update to ensure you have the latest version
Restart your terminal completely
Run claude and select your Pro account during authentication
The OAuth errors you're seeing are server-side issues caused by this ongoing incident, not problems with your local setup.
