When encountering the "DNS_PROBE_FINISHED_NO_INTERNET" error, 1. First check whether the local network connection is normal, confirm the Wi-Fi or network cable connection status, restart the router and test whether other devices can access the Internet; 2. Change the DNS server to public DNS, such as setting the preferred DNS to 8.8.8.8 and setting the alternate DNS to 1.1.1.1; 3. Clear the browser cache and system DNS cache, and use the command ipconfig /flushdns to refresh the DNS; 4. Temporarily close the firewall or antivirus software to eliminate the possibility of interception. Sequence checks can usually solve problems quickly.

If you encounter the error message "DNS_PROBE_FINISHED_NO_INTERNET", it means that your browser believes that the problem lies in DNS resolution, but there may be multiple reasons behind it. Don't rush to reinstall the system or change the network. Try the following methods first, and they can be solved in most cases.

1. Check whether the local network connection is normal

First, confirm if there is something wrong with your network. For example, is Wi-Fi disconnected? Is the network cable plugged in properly? Can I access the Internet on my mobile phone? If other devices cannot be connected, it may be a problem with the router or operator.

• Restart the router : unplug the power supply for 30 seconds before plugging in
• Check other devices : Try opening the web page with your phone or tablet
• Confirm whether the IP settings are correct : Generally, the choices are "Automatically obtain IP address" and "Automatically obtain DNS server address"

Sometimes it just disconnects temporarily, just restart.

2. Change the DNS server to public DNS

The default DNS is provided by the operator and can sometimes be unstable or contaminated. You can manually switch to public DNS provided by major manufacturers such as Google and Cloudflare.

The operation steps are as follows (taking Windows as an example):

• Open Control Panel → Network and Sharing Center → Click the currently connected network
• Click "Properties" → Double-click "Internet Protocol Version 4 (TCP/IPv4)"
• Check "Use the DNS server address below"
• enter:
  • Preferred DNS server: 8.8.8.8
  • Alternate DNS server: 1.1.1.1

Save and refresh the web page to see if there is any improvement.

3. Clear browser cache and DNS cache

Both the browser and the system cache DNS information, and once the cache expires or is incorrect, it will cause the resolution to fail.

Clear the browser cache:

• Open Chrome → Settings → Privacy and Security → Clear browsing data
• Select "All Times" in the time range, check "Cookies and other website data", "Cached pictures and files"

Clear the system DNS cache:

• Win R Open the run window and enter cmd
• Enter:

   ipconfig /flushdns

After performing these two operations, try to access the web page again.

4. Turn off the temporary test of the firewall or antivirus software

Some security software comes with network protection functions, which may accidentally intercept normal DNS requests.

• Temporarily turn off Windows Firewall (Settings → Update & Security → Windows Security Center → Firewall)
• Or exit third-party antivirus software (such as Kaspersky, 360)

If you can access the Internet at this time, it means they are doing it. You can consider replacing lighter security tools, or adjusting rules to allow DNS traffic.

Basically these common ways of handling it. It is not necessary to do each one. It is recommended to check it in order. Usually, you can do it by changing DNS or clearing the cache. This error looks scary, but it is not complicated but it is easy to ignore details.
