What Causes a 405 Response Code and How Do I Fix It? or Getting a 405 Response Code – What’s the Righ

405 errors can also pop up if your proxy (like Nginx) is misconfigured.

Had this issue where Nginx was stripping headers or blocking methods. Check your proxy config for anything like `proxy_method` or `limit_except`.

Also, try hitting the backend directly (bypassing the proxy) to see if it’s the server or the proxy causing the 405 response code.
