405 Method Not Allowed

The methods to access resources on web servers are defined in the HTTP protocol, but all web servers can be configured to allow or disallow any method.
The 405 error means that the method specified in the request is not allowed for the resource identified in the request URL.
It may be displayed because the webserver is not configured to accept requests from visitors at all. Errors with 405 codes are often returned when trying to use the POST method, while the server is not configured to allow the POST method necessary to process it.

Possible solutions

Make sure that the method you are passing is correct and is allowed by the endpoint.
