How to fix error http-405 in Windows 11

Solution Steps

1. 1 First, identify which application is showing the error. If it's a specific app, check its settings for any URL or server address. Sometimes the app has a configuration file where you can change the endpoint.
2. 2 If the error occurs in a web browser, try clearing the browser cache and cookies. Press Ctrl+Shift+Delete in Chrome or Edge, select 'All time' and clear. This can resolve stale requests.
3. 3 If it's a game or app, check for updates. Developers often fix server issues. Go to the app's official website or store page and download the latest version.
4. 4 If the error is from Windows Update, it might be a temporary server issue. Wait a few minutes and try again. You can also run the Windows Update Troubleshooter from Settings → System → Troubleshoot → Other troubleshooters.
5. 5 If the error persists, try using a different network connection (like a mobile hotspot) to see if it's a network issue. Some ISPs or proxies might block certain HTTP methods.
6. 6 As a last resort, you can use a tool like Fiddler to inspect the HTTP requests and see which method is being used. But this is advanced and not recommended for beginners.
