Unable to connect to TopStepTrader

[ActiveTrader09]

Is the Rithmic data servers down? Today, I connected to TopStepTrader from 8:30 to 11:30 am EDT with no problems. I now get the following error messages when I try to connect to TopStepTrader.

Do I need to do anything to fix this?

What version of NinjaTrader 7 are you using? Please provide the entire version number. This can be found under Help -> About (Example: 7.0.1000.X)

I am able to connect to a TopStepTrader account in NinjaTrader 7 without issue. I suspect you're experiencing this because of a local connectivity issue or because of an issue between your PC and the necessary servers.

To troubleshoot the connection issues, I recommend the following steps. Test after each step to see if the issue is resolved:

• Restart NinjaTrader
• Restart your modem and (if applicable) router
• Restart your PC
• Clear your DNS - Open the Command Prompt and run this command: ipconfig /flushdns
• 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 the (My) Documents/NinjaTrader 7 folder.
• 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.

I restarted everything, and now I am able connect to TST. I suspect it was a DNS cache issue. Anyway, thanks for the help.
