Step:4 Refreshing DNS Cache:

The process of translating domain names into numerical IP addresses is crucial for internet functionality. To prevent repetitive conversion every time a website is visited, DNS servers and browsers store address records in the DNS cache. While this speeds up loading times, it can also result in issues like the “ERR_CONNECTION_CLOSED” error when outdated entries clash with the current website version. A potential way of performing a DNS flush, which entirely purges the address cache.

You can accomplish this by executing the below command in the command line;

Command => ipconfig /flushdns

 

 

 

You can execute the below command to clear the Chrome browser’s DNS cache, it will be placed in the browser’s URL
