Clear your local DNS cache

For Windows:

1. Open the Command Prompt as an administrator. To do this, search for "cmd" in the Start menu, right-click on Command Prompt, and select Run as administrator.

2. In the Command Prompt window, type ipconfig /flushdns and press Enter.

   You should see a confirmation message: "Successfully flushed the DNS Resolver Cache."

3. Restart your machine.

For macOS:

1. Open Terminal. To do this, go to Applications > Utilities > Terminal or search for "Terminal" in Spotlight.

2. The command to clear the DNS cache varies slightly depending on your macOS version. Try one of the following:

   • For macOS Big Sur and later:
     sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder

   • For macOS Catalina and earlier:
     sudo killall -HUP mDNSResponder

3. You'll be prompted to enter your administrator password. Enter it and press Enter.
