ERR_CONNECTION_RESET is a common browser error message that shows up when a website fails to load because the connection between your browser and the server was unexpectedly closed. It basically means your browser was trying to reach the website's server, but the process got cut short unexpectedly.

If you’re running a website, seeing this error can be a real headache for your visitors. It stops them from seeing your content and can make your site look unreliable.

What causes the ERR_CONNECTION_RESET error?

Several things can trigger the ERR CONNECTION RESET error code, especially when building or managing a site. These include the following.

• Incorrect internet settings. Sometimes, your computer's proxy settings or firewall software rules might be unintentionally blocking network connections.
• Network connection issues. There could be a problem with your own internet equipment, like your router or modem, or even issues with the network cables. Interruptions during data transfer between your browser and the server can also trigger the error.
• Faulty browser extensions. Occasionally, a browser extension you've installed can interfere with how websites load, leading to these reset errors.
• VPN or antivirus software. Your VPN or antivirus might be a bit too strict and could be mistakenly interrupting legitimate connections.
• Server downtime. If the web server is down for maintenance or is struggling with too much traffic, it might reset stable connections instead of sending the web page.

Essentially, anything that disrupts the flow of communication between your browser and the website's server can trigger this error.

How to fix the ERR_CONNECTION_RESET error

Here are a few things you can try.

• Restart your router and modem.

Restart your router and modem. This can often resolve temporary glitches in your local network. Before diving into more technical fixes, make sure you have an active internet connection. You can also run basic network diagnostics using the command prompt, such as typing ipconfig /release and ipconfig /renew to refresh your IP address.

• Check your proxy settings. 

Make sure you don't have any manual proxy settings enabled unless you specifically need them. Open the Connections tab in your internet settings and select settings to ensure that you don't have any incorrect proxy configurations. If everything seems fine, verify that the connection is working properly. 

You could also try setting it to automatically detect the settings or disable proxy server access entirely to see if that resolves the issue. These adjustments are often found in your Windows internet settings, so be sure to check your system settings if you're on a PC.

• Disable antivirus or VPN temporarily. 

Try turning off your antivirus or VPN briefly to see if they're the ones causing the issue.

• Clear browsing data. 

Sometimes, old or corrupted browser data like cache and cookies in your browser can cause connection problems. Clearing cached images and other cached files might help.

• Check your internet provider. 

It's possible the problem isn't on your end. Your internet service provider might be having issues, or your connection's IP address might have been temporarily blocked.

• Try a different browser or network device. 

See if the site loads on a different browser like the Google Chrome browser or another device. This can help you figure out if the problem is specific to your current setup.

• Check your system preferences. 

If you're using a Mac, go to your System Preferences and ensure that your network and proxy settings are configured correctly.

ERR_CONNECTION_RESET when building a website

If you're encountering these connection errors while developing a website, it's a good idea to investigate both the proxy server and what's happening on your own computer.

• Server-side. Look into your hosting provider, ensure your SSL certificate is valid, and review your server's firewall settings. Even a small misconfiguration can cause problems.
• Client-side. Use your browser's developer tools (like Chrome DevTools) or your computer's network settings to see if there are any unusual restrictions.

Also, ensure your DNS address and IP version (IPv4 or IPv6) and operating system settings are properly configured for your network. Double-check your DNS settings to make sure they're not misconfigured.

FAQs about ERR_CONNECTION_RESET

Why does ERR_CONNECTION_RESET keep happening?

Often, it's due to unstable internet connection, interference from security software, or the website's server being temporarily unavailable. If the error persists, try switching to a different network or temporarily disabling your Windows firewall or proxy settings.

Can server issues cause ERR_CONNECTION_RESET?

Absolutely. If a website's server is down or its security rules are misconfigured, it can lead to connection resets. This is why website owners need to monitor their site's uptime and check server logs regularly.

Is ERR_CONNECTION_RESET a client or server error?

It can be either. Sometimes it's a problem with your web browsers or network settings, and other times the website's server is the one closing the internet connection.

How can I prevent this error on my website?

Choose a reliable hosting provider, keep your SSL certificate up to date, avoid overly strict firewall rules, and regularly test your website's connectivity from different networks and devices.
