429 Error: What It Means and How to Resolve It

3 min. read
Are you getting a 429 error on your website? That's a bummer! Don't get discouraged as we got you covered! Read on to discover what it is and how to fix it.

Many client-side errors can appear on your site and, in return, frustrate your visitors. There's the notorious 404 error that means the page you wanted to access couldn't be found on the server. Or, the 405 error that indicates that the server has rejected the specific HTTP method the web browser is using.


Another such error that can appear on your site and cause frustration in consumers is the 429 error. 


The good news is that we know what the most common causes of the error are. The bad news is that there's more than one potential culprit, so we need to try a few different things before fixing it. 


In this post, we're going to dive into what a 429 error means, its main culprits, and three different ways how you can resolve this particular issue. 


Let's dive into it!

What Does a 429 Too Many Requests Error Mean?

Error 429, also known as 429 Too Many Requests Error, is a client error that indicates that 

the user has sent too many requests in a given amount of time. 


In other words, the server is telling you: Please stop sending requests.

What Causes a 429 Error?

In some cases, when your server detects that a user is attempting to access a page over and over in a short period, it's an alert for suspicious behavior. In return, it can trigger a rate-limiting feature and show a 429 error. 


Rate limiting is often used to manage incoming and outgoing traffic to or from a network. 


Let's say that you're using a specific service's API that is configured to let 100 requests per minute. If the number of requests exceeds 100 per minute, an error will appear.


The practice of implementing rate limiting is to allow for an improved flow of data and to boost security by blocking attacks such as DDoS and preventing website crashes


In addition to rate limiting, another cause for a 429 error can be a bad plugin or a faulty theme.

How Can the 429 Error Appear?

There are several ways you can see a 429 error. Here are a few of the variations that may appear on different browsers or websites:

  • 429 Too Many Requests

  • 429 Error

  • HTTP 429

  • Error 429 (Too Many Requests)

Although they are slightly different, they all mean the same thing: a user or a snippet of code is overwhelming the server with too many requests.


In addition to the error, you may also see additional details that explain the reason for the 429 status code and how long you have to wait before you can try to log in again.

How Do I Fix a 429 Error?

In some cases, the error will go away on its own if you wait a little while. In other instances, in which the error is due to a DDoS attack or issue with a plugin, you need to be proactive in fixing the problem. 

Disable Your Plugins

Sometimes, a bad plugin can be the cause of the 429 error. The plugins that are most notorious for causing errors include:

  • Security plugins.

  • Solutions that force your website to load over HTTPS.


These plugins might send an overwhelming amount of requests to the server and surpass its rate limit, and with that, cause a 429 error. 


The fastest way to check if a plugin is causing the issue is to disable all the active plugins on your site. 


If the error disappears, it means that it was a plugin that was to blame for the 429 error. As a future tip, try to have as few plugins as possible. Install only those that are critical for your site to function properly and delete the rest.


If the error persists, then you may need to try a different method. 

Switch to a Default Theme

If a plugin isn't causing the error, it may be an issue with your active theme. The only way to check if your theme is at fault is by disabling it manually and switching to one of the default themes your CMS offers.


If a theme is what was causing the 429 error, it should be gone once it's disabled. 


Now that you got rid of your issue, consider choosing a theme that doesn't have built-in features. You can additionally get in touch with the theme's designers to inform them of the issue and ask for help in solving the error.

Contact Your Hosting Provider

If you tried disabling your plugins and your current theme but couldn't fix the 429 error, it may be time to contact your hosting provider. 


Sometimes, the reason for the error may be your server, rather than with your website.


If the issue is with the server, nothing you will do from your side will help. 


It may be possible that your hosting provider is rate-limiting. Your host may be blocking requests from certain third-party services or platforms that make too many requests to your website, including bots, crawlers, search engines, or apps like Google Search Console. 


Many bots, for example, can have a negative impact on your site, especially if they don’t follow your robots.txt. Other crawlers, like Google, are important. If this is the case with your host, make sure they limit bots and crawlers correctly. 


Even if your host isn't blocking third-party services, they can still shine some light on what may be causing the error.

Final Word

There are as many types of HTTP status codes as there are rings on the Olympic games flag. Whether your site is affected by a 404 error or 502 bad gateway, knowing what these errors indicate can save your business.
