The Hypertext Transfer Protocol (HTTP) status code 505 indicates an HTTP version not supported by the server. The server does not support, or refuses to support, the major version of HTTP that was used in the request message. The server is indicating that it is unable or unwilling to complete the request using the same major version as the client, as described in section 3.1 of the HTTP/1.1 specification.
