Meaning

Chrome cancels in-flight requests when the network configuration changes. It is usually a one-off after reconnecting, but a repeating error points to a flapping connection, a VPN that keeps reconnecting, or two adapters competing for the default route.

Common causes

  • Wi-Fi roaming between access points or switching to another network
  • VPN connecting, disconnecting or reconnecting
  • Unstable router/ISP or DHCP lease renewing
  • Multiple active adapters (Wi-Fi + Ethernet + virtual adapters)
  • Power saving turning the adapter off

⚡ Quick fix

  1. Reload the page once the connection is stable
  2. Disable unused adapters and VPN auto-reconnect loops
  3. Update the network driver and turn off adapter power saving

Detailed fix by platform

Windows

  1. Device Manager → your adapter → Power Management → untick "Allow the computer to turn off this device"
  2. ipconfig /release then ipconfig /renew then ipconfig /flushdns

Chrome

  1. Try an incognito window (extensions off) to rule out proxy/VPN extensions

How to diagnose

  1. Timing — Does it happen when switching networks or at random?
  2. VPN — Is a VPN reconnecting?
  3. Adapters — More than one active adapter?
