Error "Unable to connect to DB"

[linkcou]

Hi Team,

This morning when trying to connect to the NT8 platform after adding my credentials, i received the error attached. The platform doesn't open. I tried to restart the computer but i keep having the same problem.

Any idea how to fix it?

Hello linkcou,

Thank you for the message.

Please use the following steps to rename the database file so NinjaTrader automatically creates a new one:

• Close NinjaTrader
• Go to Documents folder > NinjaTrader 8 > db > NinjaTrader.sqlite, right-click on this file and select 'Rename' and change the name to "NinjaTrader Old.sqlite" and then click off of it anywhere to save the name change
  • Please click here for a video demonstration of how to rename the Database file

Reopen NinjaTrader and test if the error is still appearing.


If the error message is still happening, please use the following steps to send your log and trace files to the support team directly from your NinjaTrader Platform so we may investigate this behavior further:

• Attach: Attach a file, picture, or compressed file to share multiple files/pictures
• Body: Include any other information you would like to share on the situation
