Login Failed with IB: connection refused

[shicuco]

Hi, there! I've been connecting to IB for months with no issues so far. I upgraded to TWS latest build a few days ago, made a few changes to the configuration that I was not able to reset, so I decided to uninstall and reinstall TWS. But now I get this failed login error. Can you help me?
Thanks

shicuco, please ensure to be using the supported TWS release as mentioned and available in our IB connection guide - http://www.ninjatrader.com/webnew/su...ivebrokers.htm (this is currently the 906.8).

In addition, is the API enabled in our TWS settings?

Hi, Bertrand! Enabling the API did the trick! After unistalling TWS I should have followed the IB connection guide again to make it all work. My mistake. Sorry for wasting your time!
Thanks
