If you are using WordPress, there is a high chance that you may run into the ERR_CONNECTION_RESET error. This error occurs when you try to access your website from an Internet browser, and it prevents users from accessing your site. This can be frustrating because it’s hard to find out what exactly caused this problem in the first place. Fortunately, we’ve outlined some of the most common causes for this issue so that you don’t have to worry about your site being down any longer!

The request was rejected because the HTTP protocol version is not supported.

You may get this message if you are trying to access a website through your WordPress site:

“The request was rejected because the HTTP protocol version is not supported.”

This means that the browser can’t identify the protocol (like HTTP or HTTPS). You must have a bad Internet connection that restarts and resets on its own.

The browser can’t identify the protocol (like HTTP or HTTPS).

If you’re getting this error, it’s likely because the URL you’re trying to visit is incorrect. Check the website address you are trying to visit and make sure it’s correct.

  • Check the URL in your browser: If that doesn’t work, check the URL in your browser’s address bar. Are there any typos or extra characters? Make sure that you have typed out the website address correctly and haven’t missed any letters or numbers along the way.
  • Check that you have typed the URL correctly: Sometimes our fingers can get tired from typing so fast! If so, please take a break and try again later with fresh fingers!
  • Check that you’ve entered the correct protocol (HTTP or HTTPS) for each domain name as well (e.g., www vs non-www).

You may have a bad Internet connection that restarts and resets on its own.

If you are having a problem connecting to the WordPress site, the first thing you need to do is check your internet connection. If your computer or laptop is connected to the router and modem, there may be an issue with your computer itself. If you have access to another computer or device, try logging in through that device as well.

If there is still no fix for this error, then it’s a good idea to check your router and modem as well. If something has gone wrong with either of these devices, they need a replacement immediately—it could be causing other problems on your network as well!

The site you are trying to open has reached its concurrent connection limit.

  • You can increase the number of concurrent connections on your server.
  • Increase the number of concurrent connections allowed by your host.
  • Check that you have enough RAM and CPU to handle the load

Corrupted cookies or cache create this error.

Corrupted cookies or cache can also create this error.

To fix corrupted cookies:

  • Sign out of your WordPress admin panel, and then sign back in again as an administrator.
  • Navigate to your wp-config.php file, found in the root directory of your website’s installation folder (e.g., http://examplewebsite/wp-config.php).
  • Find the following code: define(‘COOKIE_DOMAIN’, ”);
  • Replace it with define(‘COOKIE_DOMAIN’, ‘yourdomainnamehere’); where you replace “yourdomainnamehere” with your actual domain name (e..g if my domain was examplewebsite I’d change it from “examplewebsite” to “examplewebsite”).
