It never passes from Verifying license

[FlowerJulian]

Hi ! I was wondering if anyone coud help me on this one. I double click on the app to open it, it pops up the 'Verifying license' chart, it disappears and then nothing happens. tried several times, then deactivated the firewall and antivirus since I read it could help, but still the same thing happens.

Windows 11, 8gb ram, Ninja trader 8.

PS: Not my native language.. in case of errors hahaha

Hello FlowerJulian,

Thank you for your post.

There seems to be a connection error between your computer and the NinjaTrader servers. I have detailed a few general network troubleshooting steps below that may resolve this error for you (test for the issue after each step):

• Restart NinjaTrader 8
• Restart your PC
• Restart your modem/router
• Ensure that all available updates for your PC are installed from the Windows Settings > Update and Security page. Be sure to close NinjaTrader and restart your computer after any updates are installed.

• Disconnect and reconnect to your network
• Disable your VPN service (if applicable)
• Clear your DNS: Open the Command Prompt > type in 'ipconfig /flushdns' > press 'Enter' on your keyboard
• Ensure that you have the Documents\NinjaTrader 8 folder on the list of exceptions for your firewall, antivirus, or backup programs and software
• If possible, try running your computer directly to your router/modem using an ethernet cable, or vice versa, through a WiFi connection if already hard-wired in

This error may also occur when using an out-of-date version of NinjaTrader. While I can see that you are using the newest version, an uninstall and re-install of NinjaTrader 8 may possibly fix this error as well.

Which version had the problem?
Which previous version did you install?

Please look at Control Center window, click on Help -> About
and reply with the version numbers ... that would be very helpful.
