    Fail to verify license

    Got this error.

    What to do?

    #2
    torroray,

    There are three main reasons why this message appears.
    • Your license is truly invalid however -which license key are you using currently under Help > License Key?
    • You have incorrectly entered the license key. Please double check to ensure that you have not accidentally entered an incorrect character or have a space at the end of your license key
    • The most common reason is that a firewall on your PC or on the network your computer is on is preventing NinjaTrader from accessing our license servers. To test this, please disable all firewalls and then restart NinjaTrader and see if it works. If yes, you just need to add ninjatrader.com to the exception list (safe list) for your firewall software
    If none of the above resolutions work, please let us know.
