What Is Client Error?
A client error refers to a situation where there was a problem on the user's device or browser that stopped it from completing its request to the server.
It means that the issue does not originate on the server side - the server is ready and waiting to respond. Rather, something goes wrong on the client side in trying to make the process of making a request happen.
Maybe the browser times out, loses internet connection briefly, encounters a software bug, or runs into permissions limitations.
Whatever the exact trigger, when the server receives no request or an invalid one, it chalks it up as a client error since the user's device fails its end.
The server can't process what never fully arrives from the client-facing roadblocks. The breakdown happens on the requester's side before the server can play its part.
Simply put, it indicates an error caused by the client's actions or the way the client's request is constructed, leading to the server's inability to fulfil the request. Such types of errors typically belong to the 400 series of HTTP status codes.
