Interactive Brokers Connection

Hello I can't connect to my TWS with S# Data Hydra. The settings are good in S# Data and TWS I see in the TWS that the connection stays in red status (disconnected) , never get stable green (attached image), and disapears after few seconds This is happening when I click the Verify button, or when I try to Download securities

The S# message is : BasketMessageAdapter 7/20/2019 8:17:18 PM Info Connecting 'Interactive Brokers: Address = 127.0.0.1:7496'.
