    Hello andrey0007,

    The error indicates NinjaTrader cannot connect to its license server to verify the license you have entered. Please check for software such as (corporate) firewalls, spyware and anti-virus software that could be blocking NinjaTrader. In some cases the modem/router has built-in software that prevents the connection to be established.

    NinjaTrader itself connects to standard web address via HTTP protocol through whatever port is defined for internet browsing on the target PC (Port 80 by default) to connect to its license server.
