The 405 Not Allowed error in Nginx is typically caused by one of the following reasons:<\/p>\n

    \n
  1. The request method is not allowed: The Nginx server configuration may restrict certain request methods (such as POST, GET, etc.), and the client sent an unauthorized request method.<\/li>\n
  2. Missing request header: Some APIs or websites may require specific request header information. If the request header is missing or incorrect, the server will return a 405 error.<\/li>\n
  3. The URL is incorrect: the requested URL may not exist or be unavailable, causing the server to be unable to handle the request, resulting in a 405 error.<\/li>\n
  4. Insufficient or incorrect access permissions: The server may require specific access permissions to process the request, and if the client does not have the correct permissions, the server will return a 405 error.<\/li>\n
  5. The configuration for handling requests is missing: The Nginx server might not be properly configured to handle specific types of requests, resulting in a 405 error.<\/li>\n
  6. Frontend-backend mismatch: If Nginx proxies to the backend server and the backend server does not support or allow the requested method, it will result in Nginx returning a 405 error.<\/li>\n<\/ol>\n

    Some ways to resolve this error include checking if the request method, request headers, and URL are correct, verifying access permissions, ensuring Nginx configuration is correct, and verifying compatibility between the frontend and backend.<\/p>\n","protected":false},"excerpt":{"rendered":"
