If the user is getting a 403 Forbidden error, ensure that the There are several ways to ensure this, but the following command will work in this case: On the server, the index file is located at /usr/share/nginx/html/index.html.The web server worker process is owned by the www-data user.

The user is trying to access the web server’s index file, from.

To give an example of troubleshooting a 403 error, assume the following situation: File PermissionsĤ03 errors commonly occur when the user that is running the web server process does not have sufficient permissions to read the file that is being accessed. If you are encountering a 403 error unexpectedly, there are a few typical causes that are explained here. The 403 status code, or a Forbidden error, means that the user made a valid request but the server is refusing to serve the request, due to a lack of permission to access the requested resource.

In this case, the user will receive a 401 response code until they provide a valid username and password (one that exists in the. This means that the user must provide credentials to be able to view the protected resource.Īn example scenario where a 401 Unauthorized error would be returned is if a user tries to access a resource that is protected by HTTP authentication, as in this Nginx tutorial. The 401 status code, or an Unauthorized error, means that the user trying to access the resource has not been authenticated or has not been authenticated correctly.

Malformed request due to human error when manually forming HTTP requests (e.g.

Malformed request due to a faulty browser.

Clearing the browser’s cache and cookies could solve this issue

The user’s cookie that is associated with the site is corrupt.

Here are a few examples of when a 400 Bad Request error might occur:

The 400 status code, or Bad Request error, means the HTTP request that was sent to the server has invalid syntax. Now that you have a high-level understanding of HTTP status codes, we will look at the commonly encountered errors.

This means that the actual status code that is returned depends on how the server software handles a particular error – this guide should generally point you in the right direction

Keep in mind that HTTP status code definitions are part of a standard that is implemented by the application that is serving requests.

For example, web servers such as Apache or Nginx produce two files called access.log and error.log that can be scanned for relevant information

Check server logs for more details about how the server is handling the requests.

When using a web browser to test a web server, refresh the browser after making server changes.

Server errors, or HTTP status codes from 500 to 599, are returned by a web server when it is aware that an error has occurred or is otherwise not able to process the request. Even though these types of errors are client-related, it is often useful to know which error code a user is encountering to determine if the potential issue can be fixed by server configuration. Client and Server Error OverviewĬlient errors, or HTTP status codes from 400 to 499, are the result of HTTP requests sent by a user client (i.e. There are many situations that could cause a web server to respond to a request with a particular error code – we will cover common potential causes and solutions. 4xx and 5xx status codes, from a system administrator’s perspective. This guide focuses on identifying and troubleshooting the most commonly encountered HTTP error codes, i.e. The class of a status code can be identified by its first digit: HTTP status codes are three-digit codes, and are grouped into five different classes. When accessing a web server or application, every HTTP request that is received by a server is responded to with an HTTP status code.
