"ERR_NETWORK_CHANGED" displays when your network connection has an issue and you cannot browse the internet. You might be unable to use other internet-connected applications due to that issue.

Your IP address is often the cause of the "ERR_NETWORK_CHANGED" message. Either the network cannot resolve the address because of problems with the Domain Name System (DNS), or the address may have abruptly changed.

How to Fix the ERR_NETWORK_CHANGED Error?

1. Restart Router
It only requires unplugging the router's power plug, waiting a minute, and then plugging it back in.

It can take the router a minute or two to fully restart after you plug it in and re-establish your connection. Return to the PC after confirming the WLAN connection by checking the router's lights.

2. Flush DNS
Press Windows + R, select cmd, and write the below command:
​​​

• IPCONFIG /FLUSHDNS
• NBTSTAT –R
• NETSH INT IP RESET
• NETSH WINSOCK RESET
  
  3. Check your proxy settings
• In Windows, open the start menu and search for “internet options,” then choose the choice on the menu.
• The Internet Properties settings window will open as a result.
• Navigate to Connections > LAN Settings from this window.

​​​


Disable the setting temporarily if it reads, "Use a proxy server for your LAN." While you're there, confirm that the setting for "Automatically detect settings" is turned on under "Automatic configuration".


​​​

4. Check your DNS settings.
Go to the Network Status screen > Advanced network settings > Change adapter options in Windows.

​​​



This page includes a list of the network connections you have access to. Right-click on it and select Properties, then go to Internet Protocol Version 4 (TCP/IPv4) > Properties.


​​​



Obtain an IP address automatically, and a DNS server address is set to be enabled on this screen by default. We advise temporarily returning to the default settings if you're using a custom IP address or DNS server.
