Encountering the 'ERR_NAME_RESOLUTION_FAILED' error in your computer's browser indicates a DNS (Domain Name System) resolution problem.
Check Your Internet Connection: The error may be temporary, and a connection issue could be causing the problem.
Clear Browser Cache: Cached data may be causing conflicts. Clear your browser's cache and cookies through the settings or preferences menu.
Flush DNS Cache: Open the Command Prompt on Windows or Terminal on macOS/Linux as an administrator and type 'ipconfig /flushdns' (Windows) or 'sudo killall -HUP mDNSResponder' (macOS/Linux). This clears the DNS cache.
Use Google's Public DNS: You can do this in your network settings.
Check Hosts File: Ensure that the domain you're trying to access is not mistakenly blocked in your computer's hosts file. The hosts file can be found in the system's 'etc' directory.
Try Another Browser: If the error persists, try accessing the website using a different browser. If successful, the problem may be specific to the original browser.
Contact Your ISP: Contact your ISP for assistance or consider using a different DNS service.
By systematically going through these troubleshooting steps, you can address the 'ERR_NAME_RESOLUTION_FAILED' error and improve your DNS resolution, allowing you to access the desired websites.
