ERR_NAME_NOT_RESOLVED: 7 Step Fix for Chrome, Edge & Firefox
The ERR_NAME_NOT_RESOLVED error occurs when the browser cannot locate the corresponding IP address for the queried domain name.
Actionable Resolution Steps
1. Verify Internet Connection & Public IP
Check if other websites load properly. Visit [WhatMyIP.site](/) to verify that your device has an active public IP and can reach the internet.
2. Disable DNS Pre-fetching in Chrome
Go to Chrome Settings > Privacy and Security > Performance, and toggle off 'Preload pages for faster browsing and searching'.
3. Flush System DNS & Restart DNS Client Service
Run Command Prompt as Administrator:
ipconfig /flushdns
net stop dnscache
net start dnscache
4. Test with an Authoritative DNS Checker
Enter the problematic URL into our [DNS Record Checker](/dns-lookup) to confirm whether global root nameservers can locate the target host.
5. Disable Active VPN or Proxy Extensions
Browser proxy extensions and misconfigured VPN tunnels frequently hijack DNS queries. Temporarily disable extensions and run a test on our [VPN Checker](/vpn-checker).
6. Power Cycle Your Wi-Fi Router
Power off your router and modem for 60 seconds to clear ISP DHCP routing tables and DNS cache buffers.
