A server error (5xx) is an HTTP status code that indicates that the server encountered an error while processing a request. This type of error occurs on the server side and can be caused by various issues such as a misconfigured server, a poorly written code, or an overload on the server.
The Server Error (5xx) status codes are typically divided into the following categories:
To fix a server error (5xx), you need to identify the root cause of the issue. You can do this by checking server logs to determine the exact error message and by reviewing any recent changes made to the Server Error (5xx) server or application. Once you have identified the problem, you can take the following steps to fix it:
It is important to care about Server Error (5xx) because they can negatively impact the user experience, and may result in lost revenue, Server Error (5xx) decreased customer satisfaction, and damage to the reputation of the website or web application.
A Server Error (5xx)
tells a website owner or developer that a user tried to reach a URL but was unable to do so. Also, if a website is accessed by search engine crawlers and they get a Server Error (5xx), they may give up and delete the URL from the search index, It may have a detrimental effect on the traffic to a website.
This error suggests that an unforeseen circumstance was encountered by the server but was not properly handled. Normally, this denotes that an application request was unable to be performed due to improper application configuration.
This error indicates that the server does not support or does not understand the capability the client has requested. This can mean that the server will take this kind of answer into consideration in the future.
This error shows that the server is a proxy or gateway and that an upstream server sent an incorrect answer. Or to put it another way, the proxy is unable to forward the request to the target server.
This error indicates that the server is temporarily incapable of handling the request, for example because it is undergoing maintenance or is experiencing excessive loads.
The Retry-After header on the server could include the anticipated duration of the delay. If there is no value in the Retry-After header, this response is functionally equivalent to response code 500.
This error tells the proxy that a server upstream is not responding to it quickly enough. This just indicates a delay in obtaining a response, which might be caused by a network or latency issue, not a fault with an upstream server.
This error shows that the major HTTP version that the request utilised is not supported by the web server. The answer includes a component that explains why the requested protocol version is not supported and lists alternative protocol versions that the server does support.
This error occurs when using Transparent Content Negotiation—a protocol that enables clients to retrieve one of several variants of a given resource. A 506 error code indicates a server configuration error, where the chosen variant starts a content negotiation, meaning that it is not appropriate as a negotiation endpoint.
This error indicates that the client request cannot be executed because the server is not able to store a representation needed to finalize the request. Similar to a 503 error, this state is transient. It frequently has to do with the server’s Memory or disc capacity restrictions.
This error occurs in the context of the WebDAV protocol. That means the server terminated a client action after spotting an endless loop. When a client submits a Web dav request with Depth: Infinity, this may occur.
This error shows that the bandwidth allotment set by the server administrator was exceeded. The server configuration specifies a bandwidth check interval, and the restriction is only reset after this time. Client requests will keep failing up until the following cycle, when the bandwidth cap is reset.
This error shows that the client did not adhere to the resource’s access policy. The client will get the data from the server they require to increase access to the resource.
This error indicates that the resource accessed requires authorization. The response should provide a link to a resource that allows users to authenticate themselves.
Many levels of the server environment might experience Server Error (5xx). These levels of a web application consist of:
In a Kubernetes application, these layers include:
Regardless of the kind of application, the following are a few typical causes of 5xx server errors:
Debugging Server-Side Scripts in Web Applications
5xx server errors are often caused by customer scripts you are running on a web server. Here are a few things you should check if your web application returns a Server Error (5xx):
