Simulation Connects then Disconnects

[MatHatter]

Hi,

I login with my credentials and click simulation then I go to connections and hit simulation and the log says it connects but then disconnects. Anyone every have this issue and know how to fix it?

I think issue started at unable to read cache data.

It's after market close so maybe they are doing maintenance on the connection?

Hello MatHatter,

Thank you for reaching out.

This behavior most commonly occurs when NinjaTrader is unable to communicate with the servers due to it being blocked by another program, or there is an issue in the path between your computer and the appropriate servers.

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.
It is common with a software update, for Windows Defender to block the app again, so please make sure exceptions for NT8 are added to any anti-virus or firewall you may have.

To resolve this, I recommend the following steps (test for the issue after each step):

• Restart your modem and (if applicable) router
• Restart your PC
• Also, ensure that your computer is not turning off your Network Adapter to conserve power:
  • Restart NinjaTrader
  • 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
• Clear your DNS
  • Open the Command Prompt
  • In the command prompt, run this command: ipconfig /flushdns
• If you are using a VPN, please turn it off and try connecting again.
• If you are not already and the option is available to you, connect to the internet using an ethernet cable. Wireless connections are significantly more unreliable.
• Ensure exceptions have been added into any firewall/antivirus/backup programs for these folders:
  • C:\Users\<your username>\Documents\NinjaTrader 8
  • C:\Program Files \NinjaTrader 8
• If the above steps do not help, contact your ISP and let them know you are experiencing a highly unstable connection. An issue of connectivity may exist on their end.

Please let me know if you are still experiencing the same after following these steps.
