How to Fix a 408 Request Timeout Error

Experiencing a 408 Request Timeout Error can be extremely frustrating. HTTP status code starting with 4XX is the client-side error code and 408 request timeout error is one of the client-side errors.

In this guide, we will learn how to fix a 408 request timeout error. Whether you're a user or a developer, we'll explore the causes behind this error and provide practical solutions.

From unraveling the technicalities to offering step-by-step troubleshooting, this guide equips you with the know-how to swiftly resolve the issue.

Before we dive into the solution let’s understand what this error actually means and how it differs from the 504 bad gateway timeout error.

What does 408 Request Timeout mean?

A 408 Request Timeout error is an HTTP status code that is returned at the client side when a server takes a longer time to process any particular request than the allocated timeout. When this happens, the server terminates the connection and thus returns 408 Request Timeout error.

It is also possible that the server could be misconfigured and result in improper request handling which may also return a 408 Request Timeout error.

408 Request Timeout Indication

• 408 Request Timeout is displayed
• It crashes the active browser window
• The browser may respond to the request slowly

Different Ways to See a 408 Request Timeout Error

There are several different ways that you might see a 408 Request Timeout error. These errors may appear differently on different web servers or hosting. Although they show different error messages, each one means the same.

• “408 Request Time-out”
• “408: Request Timeout”
• “Request Timeout”
• “The Request Has Timed Out”
• “HTTP Error 408 – Request Timeout”

How is a 408 Request Timeout error different from a 504 Gateway Timeout error?

You may have come across a similar error i.e. 504 Gateway Timeout error. Since these two errors are quite similar, you might be wondering how it is different from one another.

The 504 Gateway Timeout error occurs while acting as a gateway or proxy. On the other hand, a 408 error is returned when a request to load the web page takes longer than the server was prepared to wait.

Learn how to fix the 504 Gateway Timeout error.

According to RFC 2068, the 504 Gateway Timeout and 408 Request Timeout errors are defined as follows:

504 Gateway Timeout:

The server, while acting as a gateway or proxy, did not receive a timely response from the upstream server it accessed in attempting to complete the request.

408 Request Timeout:

The client did not produce a request within the time that the server was prepared to wait. The client MAY repeat the request without modifications at any later time.

How to Fix a 408 Request Timeout Error

In certain cases, it can be difficult to immediately determine the source of an HTTP error. Although 4xx errors are known to be client-side errors, this doesn’t mean that the server should be completely ruled out as the culprit. Below are a few things you can check, both on the client and server side in order to try and resolve a 408 error.

Fix a 408 Request Timeout error at client-side

Reload the Web Page

There are instances when this error occurs temporarily on the client side because of the browser. You can try to reload the web page or even reopen the browser to see if the error gets resolved.

Double check URL

Depending upon the configuration of your web server, the requested URL might throw a 408 request timeout error. Suppose, you are requesting a URL that requires certain permissions or credentials to get access, this might trigger a 408 error.

Check your internet connection

If there is any issue with your internet connection or it is running slow then the request made can take too long to complete. As a result, the server’s timeout exceeds and becomes idle which results in a 408 request timeout error.

Fix a 408 Request Timeout error on server-side

Check your web server’s timeout settings

Most web servers like Apache and Nginx allow website developers to set certain timeout values in the configuration file which enables you to control the time required for certain requests.

So if you are receiving the 408 timeout error, the configured timeout value might be too low. You increase the timeout value and restart the server to see if the issue is resolved.

Apache

If you’re using the Apache web server, you need to check both the .htaccess file and the Apache server config file. Inside these files look for the KeepAliveTimeout or RequestReadTimeout directives. If either of these directives is defined, increase its value and reload the webserver.

If you don’t find these directives inside the configuration file, you can add them along with their values and test a few requests by reloading the web server.

NGINX

If you’re using Nginx as a web server, open the nginx.conf file and check for directives like client_body_timeout, client_header_timeoutand keepalive_timeout and then increase their values.

If you don’t find these directives, add them inside the http or server block along with their values.

You can test a few requests by increasing their values and reloading the web server.

Check the logs

While investigating any kind of server error, it’s a good idea to check the error logs. It provides you with a whole lot of information about the error.

Additional Ways to Fix a 408 Request Timeout Error

Make sure your internet connection is stable and not experience any interruptions. Slow or unstable connections can lead to timeout errors.

Sometimes, a simple page refresh can resolve the issue if it is caused by a temporary glitch or network delay.

Cached data in your browser can sometimes cause conflicts. Clear your browser cache and try accessing the website again.

If you're a website owner, check the server load and resource utilization. If the server is overloaded, it might not be able to handle incoming requests in a timely manner. Consider optimizing your server or upgrading your hosting plan if needed.

Server logs can provide valuable information about what's causing the timeout. Look for any errors or patterns in the logs that could indicate the source of the problem.

If you're a developer, review the client-side code (JavaScript, AJAX, etc.) that is sending the request. Ensure that the code is correctly written and isn't causing delays.

Review your server's configuration settings. Ensure that the timeout settings are appropriate and not set too low. You might need to adjust timeout values in your server configuration file (e.g., Apache, Nginx).

Large payloads can cause delays, especially if the network connection is slow. Try reducing the size of the data being sent in the request.

Sometimes, the issue might be specific to a certain browser or device. Test the website or service on different browsers or devices to see if the problem persists.

If you're behind a proxy or firewall, they could be causing delays. Check if adjusting proxy or firewall settings helps resolve the issue.

If you're a website owner, using a CDN can help distribute content and reduce the load on your server, potentially alleviating timeout errors.
