Sometimes there are issues with your computer resolving Internet addresses and Domain names. There is a service called DNS (Domain Naming Service) which keeps a cache of IP addresses resolved to Internet addresses. When you have issues with DNS you need to clear out corrupted addresses and refresh – this is called Flushing your DNS.
Below are the commands to Flush DNS for Windows and MacOS.
- Use Windows search and type Command Prompt
- Right-click Command Prompt and choose Run as Administrator
- In User Account Control (UAC) pop-up just click Yes
- You will then get a black box called the Command Prompt.
- Type the following in the black box:
- Then press Enter
- Open Terminal (Application › Utilities › Terminal or click Go > Utilities > Terminal)
- Type the following into the Terminal window:
sudo killall -HUP mDNSResponder
- Then press Enter to run the command
- Type in your computer’s password when prompted. (Don’t worry it might not appear on the screen as you type).
- Then press Enter again to submit the password
- Close the Terminal.
