GitHub login not working for Sanity Studio - known issue?

I understand how frustrating it is when authentication suddenly stops working! When GitHub login isn't working across all your Sanity projects, here's what to check:

First, check the official Sanity status page: Based on the Sanity status page, all systems are currently operational, including the Authentication component which shows 100% uptime. There are no reported incidents affecting GitHub logins today.

This could be a GitHub OAuth issue: Since you're using GitHub as your login provider, the problem might be on GitHub's side rather than Sanity's. Check GitHub's status page to see if they're experiencing any OAuth or authentication issues.

Common troubleshooting steps:

• Try clearing your browser cache and cookies, then attempt to log in again
• Try a different browser or incognito/private mode to rule out browser-specific issues
• Check if you can log into GitHub directly to ensure your GitHub account is working
• If you have access to other login methods (Google, email), try those to see if it's specific to GitHub authentication

If it's affecting multiple projects and Studio versions: This strongly suggests it's either a platform-wide issue (though none is currently reported) or a GitHub OAuth problem rather than something specific to your setup.

Where to get help: If the status pages don't show any issues and you're still blocked:

• The Sanity Community Slack is usually the fastest place to check if others are experiencing the same problem and get real-time updates from the Sanity team
• You can also post on Sanity's community forums for assistance
• Subscribe to updates on the Sanity status page to be notified of any future incidents

Given that you mentioned this is happening across different Studio versions and all your projects, I'd recommend checking GitHub's status first, then reaching out to the Sanity Community Slack to see if others are experiencing similar issues.
