    Entermittent Connection

    Hello,

    I'm having a connection issue with NT8. NT8 loses connection then reconnects nearly two dozen times a day. Connection loss is usually 1-2 seconds but it is constantly disabling my automated Strategy. Can someone please provide me with the Ports and IP's for Forwarding NT8 Platform as well as for NinjaTrader's Live Data Feed.

    Maybe doing this will solve my issues. I have tested and monitored my Internet Providers connection and determined that I am not losing internet connection throughout the day. As well as consistent Upload and Download speeds throughout the day.

    Any help with this would be appreciated!

    Thanks.

    Hello GwFutures1988,

    Thank you for the note.

    When we see messages about "Connection Lost", "Slow", or "Unable to reach the server", this normally means that the Internet, Modem/Router, or another program is stopping NinjaTrader from maintaining a stable connection to the necessary servers.

    Please know that a connection state between NinjaTrader and your broker/market data vendor is not dictated by NinjaTrader.
    • The NinjaTrader application only reports the connection state as it is reported by the API you are connected through.
    • NinjaTrader behaves like a radio receiver in that it receives signals from the connected server. If the signals are not coming through, the underlying broker/market data vendor API reports this to the NinjaTrader application which in turn reports this back to you. Once a loss of connection is reported, NinjaTrader or the underlying API will continuously try to re-establish a connection.

    Please perform the steps below to troubleshoot the local network and narrow in on what could be causing these network/connection issues. Please restart NinjaTrader after each set of steps and try connecting again.
    • Begin by restarting your Modem, Router, and PC to refresh the internet connection.
    • Connect your PC directly to the Modem with an Ethernet cable if possible.
    • Ensure that NinjaTrader has been allowed through the Windows Firewall on all networks. Please follow along with this infographic:
    • Ensure that NinjaTrader has been added to any 'Exceptions' or 'Allowed Programs/Apps' kind of list within your antivirus software.
      • If you need to add NinjaTrader manually, the file path is as follows:
        • This PC > Local Disk (C: > Program Files > NinjaTrader 8 > bin > NinjaTrader.exe
    • If you are using a VPN, turn it Off
    • Clear your DNS
      • Open the Command Prompt by clicking the Windows icon and typing "Command"
      • Select 'Command Prompt'
      • Either copy and paste or type the following command: ipconfig /flushdns
      • Press Enter to make it run

    If the platform is still losing connection, you may use these additional steps and questions to look into the network issues further:
    • If you have a 2nd computer at your location you can install NinjaTrader on, do that and try connecting to the account
      • If the connection is still being lost, that points to the Network/Internet connection
      • If it works, that points to something on the original PC causing the connection loss
    • If you have a 2nd connection at your location like a mobile hotspot, connect to it and then try to connect to your account
      • If it is still blocked, this points to something with the Account or local PC/Platform settings
      • If it works, this points to the Network/Internet Connection in use

    If you perform all of the steps above and are still unable to connect, there are no further steps that we would be able to recommend as this indicates a problem somewhere further down the network path. If the issue persists after completing all of the steps above, you must contact your ISP or a Network Technician and let them know you are experiencing network connectivity issues to the following IP Addresses and get further help looking into what is preventing the connection.
