Logon failed

[milespfarrell]

I have not been able to logon to my account today, when I open NinjaTrader 8 to open my new charts the error message "My NinjaTrader Continuum; Network connection failed to the Data Server System is unavailable. (Logon failed)" will pop up. I have restarted my computer and NinjaTrader, I am using a wireless connection at the moment.

Hello milespfarrell,

Thank you for the note.

This normally means that the Internet, Modem/Router, or another program is stopping NinjaTrader from creating 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.

Restart NinjaTrader after each of the following steps and test the connection 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:

• Click here to see the infographic on allowing NinjaTrader through the Firewall

• 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 (x86) > NinjaTrader 8 > bin64 > NinjaTrader.exe
• If you are unsure of how to do this, what antivirus software is on your computer?

• Ensure that your computer is not turning off your Network Adapter to conserve power:

• Right-click on your Start button
• Select 'Device Manager'
• Expand 'Network Adapters'
• Right-click on your Network Adapter and select Properties > Power Management
• Uncheck 'Allow the computer to turn off this device to save power' option
• Click 'OK' to save the changes
• Do this for all Network Adapters
  • Click here for a video on how to check this setting

• 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 you are still unable to connect after performing all of the steps above, please write in to Platform Support with your Log and Trace files directly so we may provide further information on your computer and files specifically:

• Open Windows File Explorer (hotkey = Windows key + E) Then navigate to, "Documents" (sometimes called, "My Documents") > 'NinjaTrader 8' folder or "NinjaTrader 7' folder
• Right-click on the 'log' and 'trace' folders and select Send To> Compressed (zipped) Folder.
• Send the 2 compressed folders as attachments to PlatformSupport[AT]NinjaTrader[DOT]com

• Once complete, you can delete these compressed folders.
  • Please click this Blue text to see a video demonstration of how to send these files
