Different Methods to Fix a 408 Request Timeout Error

It is very difficult to detect the source of the HTTP error. Although the 4xx series error is known to be the client-side errors. But it doesn’t mean that the server is completely ruled out as the culprit.

Method 1) Client Side fixes

Below are a few things you can check on the client side in order to fix the 408 Request Timeout Error.

1. Double Check the URL

Sometimes, the cause behind the error is the URL you are requesting.

Now, suppose that you are requesting a URL that requires certain credentials to access and depending on how the server is configured, this could trigger a 408 response from the server. Or you are requesting a website URL from the saved bookmark that not exists.

2. Check your Internet Connection

Try to check your internet connection. If it is slow, then this could take too long to complete the request. As a result, the server timeout value exceeded and it becomes idle. This will returns 408 HTTP Status Code.

3. Try Reloading the Page

This is the easiest way to get rid of the error. Sometimes, there is a temporary problem on the client side or even the server side. Try to refresh the page that you are trying to access to see if the error has been resolved or not.

4. Rollback Recent Upgrades

If you have recently updated the WordPress just before the 408 Request Timeout appeared, you may need to rollback to the previous version.

Similarly, any extension, any modules or even any plugin or theme that you may have recently upgraded can also cause server-side issues, so retrieving to the previous version of those may also help.

Method 2) Server Side Fixes

Below are a few things you can check, on the server side in order to fix the 408 Request Timeout Error.

1. Check your Web Server’s Timeout Settings

It is possible that your web server’s timeout value is less than that of the client request time. Apache, Nginx is the web servers that allows web developers to set some timeout values so that the request is not open for a long time.

Moreover, if you are receiving a continuous 408 request timeout error then, this might be the small timeout value.

If we talk about the Apache Server, check for the .htaccess file as well as the Apache server config file. Look for: KeepAliveTimeout or RequestReadTimeout directives

In the case of the Nginx Server, Open the nginx.conf file and check for directives such as client_body_timeout, client_header_timeout or keepalive_timeout

If either of these directives is defined, try increasing their values, reload the web server and try again.

2. Check the Logs

It is always good to check the server’s error logs. This may provide you with information in order to help you resolve the issue ( like what is the nature of the error? or from where it is originated ).
