    In Windows I entered the "ipconfig /flushdns" command and received the following: "The requested operation requires elevation." What does this mean?

    It is because you don't have administrative access. Open your cmd using administrator access (usually known as "Run As Administrator").

    Your wifi firewall or the country may have some have censorship. Change your VPN to see if that works.

    It may be your internet connection. Unplug the device, wait 30 seconds and plug it back in.

    Try to flushdns and maybe check your connection to the Internet. If not, check your firewall or browser, as both may be blocking your connection to the website.

    It is very hard to do it on mobile, as many companies won't let you use a command prompt due to the operating system and applications being proprietary software.
