ERR_NETWORK_CHANGED: How to Fix It Fast

by

ERR_CONNECTION_RESET means the connection between your browser and the website was forcibly closed before any data could be transferred. The browser started the connection, but something interrupted it with a TCP Reset (RST) packet.

This is one of the most common Chrome network errors. In most cases the problem is on your side (network, VPN, antivirus, or browser), not on the website itself.

Quick Fix Checklist

  • Reload the page (or hard refresh with Ctrl + F5).
  • Disable VPN or proxy completely.
  • Restart your router and reconnect to Wi-Fi.
  • Clear browser cache and cookies.
  • Temporarily disable antivirus / firewall web protection.
  • Flush DNS and reset TCP/IP settings.
  • Try another browser or network (mobile data).

What Does ERR_CONNECTION_RESET Mean?

When you open a website, your browser establishes a TCP connection with the server. If that connection is abruptly terminated (by a TCP RST packet), Chrome shows ERR_CONNECTION_RESET.

You will usually see the message:

“This site can’t be reached
The connection was reset.”

In Firefox the same problem appears as PR_CONNECT_RESET_ERROR.

Key point: the connection started, but was killed mid-way. This is different from:

  • ERR_CONNECTION_REFUSED — the server rejected the connection from the beginning
  • ERR_CONNECTION_TIMED_OUT — no response at all
  • ERR_NAME_NOT_RESOLVED — DNS failed

Main Causes of ERR_CONNECTION_RESET

  • VPN or Proxy — the most common cause. VPN tunnels frequently drop or reset connections.
  • Unstable internet / Wi-Fi — weak signal, packet loss, or frequent reconnects.
  • Antivirus or Firewall — especially HTTPS scanning / web shields that interrupt traffic.
  • Corrupted browser cache or cookies.
  • Corrupted TCP/IP or Winsock stack on Windows.
  • Chrome socket pool issues (Chrome-specific).
  • Router or ISP problems.
  • Server-side issues (less common) — overloaded server or aggressive firewall on the website.

Step-by-Step Fixes

1. Disable VPN and Proxy

Completely quit your VPN application (not just disconnect). Also disable any proxy settings:

  1. Go to Windows Settings → Network & internet → Proxy
  2. Turn off “Use a proxy server”

Then reload the page.

2. Restart Your Router and Device

Unplug the router for 30–60 seconds, plug it back in, wait until it fully boots, then restart your computer or phone.

3. Clear Browser Cache and Cookies

In Chrome:

  1. Press Ctrl + Shift + Delete
  2. Select “Cached images and files” and “Cookies and other site data”
  3. Time range → All time → Clear data

Also try an Incognito window to rule out extensions.

4. Temporarily Disable Antivirus and Firewall

Security software (especially Kaspersky, Avast, ESET, Norton, Windows Defender with network protection) often causes this error by inspecting HTTPS traffic. Disable the web shield / HTTPS scanning for a few minutes and test again.

5. Flush DNS and Reset Network Stack (Windows)

Open Command Prompt as Administrator and run these commands one by one:

netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns

Restart your computer after running them.

On macOS:

sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder

6. Flush Chrome Socket Pool (Chrome-specific fix)

  1. Type chrome://net-internals/#sockets in the address bar
  2. Click Flush socket pools
  3. Also go to chrome://net-internals/#dns → Clear host cache

7. Disable Experimental QUIC Protocol (if Google sites fail)

If the error happens mainly on Google, YouTube, or other Google services:

  1. Go to chrome://flags
  2. Search for “Experimental QUIC protocol”
  3. Set it to Disabled
  4. Relaunch Chrome

8. Reset Network Settings Completely

Windows Settings → Network & internet → Advanced network settings → Network reset.

9. Test on Another Network

Switch to mobile data or another Wi-Fi. If the site loads, the problem is with your original network or router.

When the Problem Is on the Website Side

If the error appears only on one site and works on other devices/networks, the issue is likely server-side (overloaded server, aggressive firewall, or misconfigured load balancer). In this case there is little you can do except wait or contact the website owner.

FAQ

Is ERR_CONNECTION_RESET dangerous?
No. It is a network connectivity error, not a security threat.

Why does it happen only in Chrome?
The code is specific to Chromium browsers (Chrome, Edge, Opera). Firefox shows a similar error with different wording.

Does restarting the router really help?
Yes — very often. Routers can hold broken connection states that cause repeated resets.

Related Errors

Summary: Start by disabling VPN and antivirus, then clear cache and reset the network stack. In the majority of cases one of these steps permanently solves ERR_CONNECTION_RESET.
