Answer 1

Its a Request Timeout

The client did not produce a request within the time that the server was prepared to wait. The client MAY repeat the request without modifications at any later time.

See HTTP/1.1 Status code definitions

Answer 2

408 is really an HTTP status code, and it means that your request timed out:

408 Request Timeout

The server timed out waiting for the request.[2] According to W3 HTTP specifications: "The client did not produce a request within the time that the server was prepared to wait. The client MAY repeat the request without modifications at any later time."
