How to Fix
Step-by-Step Solutions

Make sure the key you’re using is active and has the correct permissions. An expired or revoked key will trigger KB5041580.
curl -H "Authorization: Bearer YOUR_API_KEY" https://api.example.com/docs - Update Endpoint URLs
Replace any old or deprecated URLs in your code or configuration files with the current API endpoints.
sed -i 's/old.api.example.com/new.api.example.com/g' config.yaml - Clear Browser Cache
A stale cache can serve outdated error pages. Clear cache or use incognito mode to test.
chrome://settings/clearBrowserData - Upgrade SDK
Ensure you’re using the latest SDK version that supports the current API.
npm install @api/sdk@latest - Check Network Settings
Verify that your network or firewall isn’t blocking the API domain or ports.
