The 408 Request Timeout is an HTTP response status code that indicates that the server has not received a complete request from the client within the time frame specified by the server. The 408 Request Timeout error code is similar to the 504 Gateway Timeout error we discussed in a previous article, which indicates that a server acting as a gateway or proxy has had a timeout. However, the 408 Request Timeout error is not a message from a gateway or proxy server located somewhere in the node chain, but a direct message from the active server to which the client has connected (such as a Web server).
It can be difficult to find the cause of unexpected HTTP response codes, and the 408 Request Timeout error code is no exception. With a potential set of more than 50 status codes used to represent the complex relationship between the client, a Web application, a Web server, and (possibly) multiple third-party Web services, it can be difficult to determine the cause of a particular status code, even in the best of circumstances.
How you might see a 408 application timeout error:
There are several ways to view a 408 Request Timeout error. The following list provides an overview of some of these variations, which may occur depending on the web server you are using. Although they are slightly different, they all have the same meaning.
- 408 Request Time-out
- Request Timeout
- The Request Has Timed Out
- 408: Request Timeout
- HTTP Error 408 – Request Timeout
How to Fix 408 Request Timeout Error
Check the URL
Before you embark on a scavenger hunt, the first thing to do is to look at the URL you entered. The URL you have chosen may no longer be accessible to you. This is especially the case if you try to access the target website with old bookmarks. If the website in question has made changes to the permissions or permitted request methods in the meantime, or has switched to HTTPS, it is very likely that it is no longer the registered link that leads to the website, but the HTTP-408 or similar error messages. Therefore, ensure that the URL entered is correct and up-to-date to avoid this source of error.
Reload the page
Try the web page again by clicking the refresh button or by trying the URL in the address bar again. Often a slow connection causes a delay that triggers the 408 Request Timeout error, and this delay is often temporary. Retry the page will often be successful.
Check your Internet connection
A slow Internet connection or network interruption is also a major cause of the 408 request delay error. To illustrate this, open another web page and check your Internet connection to see if it is working properly.
If the real culprit is related to your Internet connection, it can take a long time to process the application. If the server timeout value is exceeded, the error will be displayed accordingly.
Come back later
The 408 Request Timeout error is a common error message on popular websites when a large increase in traffic (that’s you!) overloads servers. When visitors leave the website, the chances of a successful layout for you increase.
Error 408 Request Timeout is quite explicit. It tells the client that the request has expired and the server has terminated the connection. If you encounter a 408 error, try using the troubleshooting suggestions mentioned in the sections above to hopefully resolve the problem.
