How to Finally Fix the Frustrating ERR_CONNECTION_RESET Error

As an experienced web developer and WordPress expert with over 15 years in the field, I know firsthand how frustrating the ERR_CONNECTION_RESET error can be. This vague browser error prevents you from accessing websites and can seriously impact your site‘s performance and search engine rankings if left unresolved.

In this comprehensive guide, I‘ll draw upon my technical knowledge to explain exactly what causes this error, the risks it poses, and – most importantly – how to properly fix it for good.

What Is ERR_CONNECTION_RESET and Why Does It Happen?

The ERR_CONNECTION_RESET message is a Chrome browser error that occurs when your computer initiates a connection to a web server but cannot establish the handshake required to receive data back.

Stats show this is one of the most common connectivity errors – according to Cloudflare, ERR_CONNECTION_RESET accounts for roughly 15% of all browser errors related to dropped connections.

This error typically appears if:

• Your browser‘s DNS cache contains an outdated IP address for the domain.
• Issues with your internet connection, router settings, or network adapter disrupt the connection.
• Security software or firewalls wrongly block access to the site.
• The website itself is down or unreachable due to server problems.

The end result? The browser automatically resets the connection for security, fails to load the site, and displays the unhelpful ERR_CONNECTION_RESET message.

The Dangers of Ignoring This Error

Many users brush off this error at first, but consistently encountering ERR_CONNECTION_RESET can seriously impact your website‘s performance and analytics.

Potential consequences include:

• Loss of visitors – Any user receiving this error will be unable to access your content.

• Higher bounce rate – Visitors will leave your site immediately if unable to view pages.

• Lower rankings – Inability to access the site hurts its indexing and SEO.

• Skewed analytics – Analytics will fail to count visits and record behavior of affected users.

Let‘s go through the steps I recommend for accurately diagnosing the cause and fixing ERR_CONNECTION_RESET for good.

Step-by-Step Guide to Resolve the Error

Based on my technical experience, follow this methodical troubleshooting approach:

Confirm the Site Is Up

First, verify the website itself is up and running using a tool like IsItWP. If it‘s down, the owner needs to resolve the issue. But if it‘s up, troubleshoot your computer‘s connection.

Restart Your Router, Modem, and Computer

Restarting your networking equipment and computer is an easy first step. This will clear any corrupt memory or temporary glitches disrupting the connection. Wait a minute or two for the reboot before retesting the site.

Disable Browser Extensions and Apps

Browser extensions like ad blockers, VPNs, and privacy plugins can interfere with connections to certain sites. Temporarily disabling all extensions is worth trying.

Clear Browser Cache and Hard Refresh

Your browser caches files locally to speed up page loads. But corrupted cache data can cause errors. Clearing your browser cache forces fresh files to be loaded. On Windows, you can also hard refresh by pressing CTRL + F5.

Try Alternate Devices and Browsers

Check if the error occurs on other devices connected to the same Wi-Fi. Trying alternate browsers like Firefox or Safari can also help isolate the issue.

Flush DNS Cache

Outdated DNS records are a common cause of ERR_CONNECTION_RESET. Flushing these cached records fetches the latest IP address for the domain. Learn how to flush DNS cache.

Change DNS Server

Using public DNS servers from Google or Cloudflare often resolves connectivity problems caused by ISP-assigned DNS servers.

Here are the top public DNS servers I recommend:

• Google – 8.8.8.8 / 8.8.4.4
• Cloudflare – 1.1.1.1 / 1.0.0.1
• OpenDNS – 208.67.222.222 / 208.67.220.220

Disable Any Proxy Connections

Proxy servers help anonymize your browsing activity but can also disrupt connections. Disabling any proxies is worth testing.

Whitelist Site in Firewall and Antivirus

If you use firewalls or antivirus software, try adding the problematic domain to a safe list or whitelist. This prevents false positives blocking legitimate sites.

Update Network Adapter Drivers

Outdated or corrupt network adapter drivers in Windows can cause connectivity issues. Check your manufacturer‘s website for the latest driver updates.

Reset TCP/IP Stack

As a last resort in Windows, open Command Prompt as admin and enter:

netsh int ip reset 
netsh winsock reset

This resets your TCP/IP and Winsock settings to defaults which may resolve stubborn network errors.

Still seeing ERR_CONNECTION_RESET errors? The underlying problem may lie with the web host. Contact their support team to troubleshoot server-related causes.

Use Website Monitoring to Stay Ahead of Issues

As a webmaster, I recommend proactive monitoring with tools like UptimeRobot to receive instant alerts if your site goes down or becomes unreachable. Addressing hosting problems quickly limits disruption and prevents cascading issues like mass ERR_CONNECTION_RESET errors for your users.

Why Does This Error Happen on Only One Site?

In some cases, the error may occur consistently on just a single website while all other sites work fine.

Based on my experience, this typically indicates:

• The site recently changed domains or hosting providers. Your DNS still points to the old IP.

• The server‘s firewall is misconfigured to block traffic from your IP range or region.

• An issue with incompatible port settings between your network and their server.

• The website has intentionally blocked your IP due to suspicious traffic patterns such as scraping.

If the error persists after flushing your DNS and trying other devices, the site owner needs to investigate and fix restrictive server settings or firewall rules blocking your access.

Best Practices to Avoid ERR_CONNECTION_RESET Errors

Follow these pro tips to avoid headaches from ERR_CONNECTION_RESET errors going forward:

✅ Clear your browser cache and flush DNS regularly

✅ Keep network drivers, router firmware, and OS up to date

✅ Use reliable public DNS servers like Google or Cloudflare

✅ Monitor your sites‘ uptime and server responses

✅ Whitelist trusted domains in firewalls and antivirus tools

✅ Disable unnecessary proxies, VPNs, and browser extensions
