What Causes the ERR_NETWORK_CHANGED Error?
Your computer can also develop temporary glitches in its operating system or network services. A simple restart is a quick and easy way to fix them and start fresh.
- Unstable Wi-Fi Connection: Brief drops in signal or switching between your router’s 2.4GHz and 5GHz bands can interrupt Chrome’s connection.
- Switching Between Networks: Moving from Ethernet to Wi-Fi, or from Wi-Fi to mobile data, forces Chrome to re-establish the connection.
- VPNs and Proxy Servers: Connecting, disconnecting, or switching VPN servers (or having a proxy enabled without realizing it) alters your network path.
- Waking Your Computer from Sleep Mode: Your device’s network adapter may take a moment to reconnect, during which Chrome shows the error.
- Faulty Network Hardware: Loose cables, an ageing router, or a failing modem can cause intermittent drops.
- Outdated or Corrupt Network Drivers: If your network adapter drivers aren’t working properly, you’ll experience more frequent connection issues.
- DNS Cache Issues: An outdated or corrupted DNS cache can send Chrome to the wrong address.
Chrome stores temporary data (cache and cookies) to help websites load faster. Sometimes, these files can become outdated or corrupt, especially after a network change, causing conflicts.
