nginx 405 status code error

10 min read

The 405 status code error in NGINX indicates that the HTTP method used in the request is not allowed for the requested resource.

Here are some common reasons for the 405 error and their possible solutions:

  1. Incorrect HTTP Method: Ensure that you are using the correct HTTP method (GET, POST, PUT, DELETE, etc.) for the requested resource. Double-check your request and adjust the method accordingly.

  2. Missing Required Headers: Some APIs or websites require specific headers to be included in the request. Make sure you have included all the necessary headers, as stated in the API documentation or website instructions.

  3. Misconfigured NGINX Server: Check your NGINX configuration files to ensure that the server block handling the request is correctly configured. Look for any misconfigured location blocks or incorrect handling of specific HTTP methods.

  4. Incomplete or Invalid Request: Ensure that your request is complete and valid. Make sure you have provided all the necessary data and parameters in the request payload or query string.

  5. Access Control Restrictions: The server may have configured Access Control List (ACL) or other access restrictions that limit the allowed HTTP methods for specific resources. Check the server configuration and adjust the ACL rules if necessary.

  6. Software or Plugin Conflict: If you are using NGINX with other software or plugins, such as load balancers or firewall modules, they might interfere with the request and cause the 405 error. Temporarily disable any additional modules or plugins to identify and resolve conflicts.

Overall, the specific resolution for the 405 error in NGINX depends on the root cause. Reviewing the NGINX server configuration file, checking for any missing headers or invalid requests, and ensuring that the correct HTTP method is used are good starting points for troubleshooting.
