Understanding HTTP 4XX Client Error Response Codes
To indicate client errors, all error codes within the 4XX category are used. These codes indicate that the client can fix the problem by taking appropriate actions, such as changing the request or verifying.
HTTP 4XX error codes, in general, are used to notify the user that there is a problem. These codes indicate errors that can easily be fixed by changing or completely changing the client’s request. These errors are not caused by the server.
What is the best time to return 4XX and 5XX status codes to the client?
Status codes 4XX are used to notify clients that there is a problem on their end. They tell clients that the server is fine and that to fix the problem they need to change the content, form or type of their request. They also inform them that it is futile to re-transmit the same request to server because the error is on client’s side.
These errors are often used by clients who are familiar to the error to provide a hint to the client as to how they can fix it. A client that receives a 404 Not Found status code will be able to tell that the requested information is not available and should submit another request. This may indicate that an error in the URL is needed.
The 5XX status codes, on the other hand, are used to indicate that the server is having problems. This status code informs the user that their request was valid and that they did not receive the response they expected due to an error on the server’s side. A 5XX status code informs the user that they don’t need to modify their request. The status code also suggests that the user can retransmit the request to resolve the problem. It also lets the client know that retransmission may not be successful and that they have no control over it.
An example of such a situation is when the client uses an API and has a problem with its database. The client might not be able save a record if the database is corrupted or unreachable. A 5XX status code is appropriate in such cases.
It is important that you clearly state the error and the reasons why it did not happen. This helps avoid frustration from the client. It will help the client to understand what went wrong and what solutions they can expect.
With explanation, here is a list of 4XX HTTP status codes
These are some common examples of codes within this family.

You can fix this error by changing the request. The correct response will be received from the server if you update the URL to reference a user actually recognized by GitHub.
405 Status Code — Not Allowed Code
You can set up a web server to restrict the access methods that its resources can be accessed. This will result in ntp 4xx errors if you try to access the resource via any method that is not permitted. This error can be triggered in certain cases if a web server isn’t configured for access.
406 — Not Acceptable
This response is provided by the server to the client in the event that the requested resource does not exist in the format requested. You may find that the resource is in a different format or language than what you are asking.

408 — Request timeout
This response is generated when a client does not respond to a request within the specified window. This is often a sign of connectivity issues or an overloaded webserver. Sometimes, it is enough to resolve the problem by making the same request again at a later date.
409 — Conflict
A 409 error code indicates that there is a problem with an already existing resource. This error code is displayed when the server encounters an application-specific conflict.

412 — Precondition Failed
Sometimes, servers are configured to accept requests only if certain conditions are met. The server will refuse to allow clients access to the resource if any of the preconditions are not met. This error will be returned by the webserver.
413 — Request Entry Too Large
Sometimes, server capabilities or willingness to process requests are limited. The server will return an error code if a request exceeds the limit. The server may close the connection to prevent the client from completing the request. One common example is one that involves a file upload. The upload might fail if there is a limit to the file size.
414 — Request URL Too Long
This is similar to the 413 error code. It is generated when the request exceeds the server’s processing capabilities. It is caused when the Request URL length exceeds the limit. This limitation on URL length is often put in place to prevent attacks or keep clients from falling into endless cycles of redirection.
415 — Unsupported Media Type
This error is caused by the web server refusing to service a request due to the format of the request not being supported by the resource.
416 — Not Satisfiable Range
This error will be displayed to a client if the request includes range-specifier values beyond what is permitted for the resource. If the Range requested by the client is 500-1500 and the image resource contains 1000 bytes, the server will not be capable of fulfilling this request. It will return a 416 error code.
