408 error

The 408 error, officially known as “408 Request Timeout,” is an HTTP status code that pops up when a client (like your web browser) takes too long to send a full request to the server. The server got impatient and basically hung up.

If you are operating a website and this happens, it is generally an indicator of a snag in the connection process. It may not necessarily be a major issue every time, but frequent occurrences certainly warrant a closer look.

What causes a 408 error?

There are various reasons why this timeout occurs.

  • Slow internet connection. If your web connection is slow, your browser may not be able to get the full request to the server within the normal time frame.
  • Server overload. Similar to a busy phone line, if the server of the website is filled with too many requests, it may take too long to answer each of them.
  • Incorrect client configuration. Occasionally, the issue is with your own setup – maybe your browser, firewall, or DNS settings are blocking the connection.
  • Large or complex requests. Transmitting lots of data or making requests that need excessive processing can sometimes result in a timeout.

408 versus other timeout errors

It's simple to confuse a 408 with other comparable errors, such as the 504 Gateway Timeout. This is the key difference.

  • A 408 error indicates that your browser was too slow to send the initial request to the server.
  • A 504 error means the server took too long waiting for a response from another server.

Think of the 408 as your server saying, “I waited, but you never said anything.”

Fixing a 408 error on your website

If your website visitors are encountering 408 errors, here are some steps you can take to investigate.

1. Verify your hosting configuration

Ensure your hosting company is not down or experiencing high traffic. Some managed hosting plans automatically scale resources, but others may require your intervention.

2. Test your site speed

Utilize tools such as Google PageSpeed Insights or GTmetrix to determine whether your site has any performance bottlenecks that may be causing it to slow down.

3. Optimize server response time

Optimize your website's code, avoid unnecessary redirects, and reduce the usage of third-party scripts. A cleaner, lighter site is more likely to be quicker.

4. Check DNS settings

Incorrect or outdated DNS settings may result in delays or failures when making connections. Check that your DNS servers are working well and correctly configured.

5. Track request logs

Check your server logs or use website monitoring tools to look for patterns in the failed requests. This can help you decide whether the errors are one-off or recurring and possibly identify the cause.

FAQs about the 408 error

Is a 408 error caused by the user or the website?

It can be either! Perhaps a slow connection on the user's end is the problem or server lag on your website can also lead to timeouts.

Can a 408 error hurt my website's SEO?

Occasional 408 errors likely won't hurt your SEO. However, if your site frequently times out and search engines can't access your pages, it could negatively affect your rankings over time.

How long does a 408 error last?

Usually, it's temporary. Refreshing the page or having the user re-establish their connection often resolves it. But if it keeps happening, there might be a server-side issue that needs attention.

Should I create a custom 408 error page?

Absolutely! A custom 408 page can reassure your visitors that the problem is likely temporary. Let them know you're aware of the issue and provide a simple way to retry or go back to your homepage.
