Detailed explanation-1: -In computer network communications, the HTTP 404, 404 not found, 404, 404 error, page not found or file not found error message is a hypertext transfer protocol (HTTP) standard response code, to indicate that the browser was able to communicate with a given server, but the server could not find what was requested.

Detailed explanation-2: -400 errors indicate an invalid request, which means either that mandatory parameters are missing, or that syntactically invalid parameter values have been detected (for example an expected URL being text only). 404 errors indicate that a requested API service cannot be found, or that a requested entity cannot be found.

Detailed explanation-3: -The 403 response code means that the visitor (Googlebot in this case) is prohibited from visiting the webpage. The 404 response code tells Googlebot that the webpage is entirely gone. Server error response code 429 means “too many requests” and that’s a valid error response.
