Quick Summary
The "ERR_NAME_NOT_RESOLVED" error in Chrome indicates that your browser is unable to find the server at the address you entered. This typically means there's a problem with the Domain Name System (DNS) server not being able to translate the website's address (e.g., www.example.com) into an IP address.
Common Causes
- Incorrect Website Address: The web address typed into the browser's address bar might be incorrect, containing typos or invalid characters.
- DNS Server Issues: The DNS server your computer is using might be temporarily unavailable, experiencing issues, or not configured correctly.
- Internet Connection Problems: Your computer may be experiencing a general internet connectivity issue, preventing it from reaching the DNS server.
- Chrome Browser Cache: Outdated or corrupt DNS cache stored in your Chrome browser can cause resolution problems.
- Firewall or Antivirus Interference: Your firewall or antivirus software might be blocking Chrome from accessing the DNS server.
- Router Problems: The router may have issues that are preventing requests from being properly sent to the DNS server.
Step-by-Step Fixes
Method 1: Check the Website Address
Step 1: Carefully check the website address in the address bar for any typos or errors.
Step 2: Ensure that the address is spelled correctly and includes the correct domain extension (e.g., .com, .org, .net).
Step 3: Try navigating to a well-known website (e.g., google.com, facebook.com) to see if the issue is specific to certain websites.
Method 2: Clear Chrome's DNS Cache
Step 1: Open Chrome and type chrome://net-internals/#dns into the address bar and press Enter.
Step 2: Click the Clear host cache button.
Step 3: Restart Chrome.

Step 1: Open Command Prompt as an administrator. Search for “cmd”, right click and select “Run as administrator.”
Step 2: Type ipconfig /flushdns and press Enter.
Step 3: Type ipconfig /release and press Enter.
Step 4: Type ipconfig /renew and press Enter.
Step 5: Restart your computer.

Step 2: Right-click on your active network connection (Ethernet or Wi-Fi) and select Properties.
Step 3: Select Internet Protocol Version 4 (TCP/IPv4) and click Properties.
Step 4: Select Use the following DNS server addresses.
Step 5: Enter a public DNS server address, such as Google's (8.8.8.8 for Preferred DNS server, 8.8.4.4 for Alternate DNS server) or Cloudflare's (1.1.1.1 and 1.0.0.1).
Step 6: Click OK and close all windows.
Method 6: Disable Conflicting Applications
Step 1: Temporarily disable your firewall or antivirus software.
Step 2: Try to access the website again.
