I was able to setup my odbc connection to ec2 instance successfully using ssh tunnel.
However, I'm getting error "6: (6) Internal Error (Exception)." when I use the same odbc connection from SQL Assistant.
I am using version 16.20 on both TTU and ODBC driver (32-bit).
I have also tried Teradata Studio and Teradata Studio Express version 10.20. Both loaded the splash screen and then closed with no error showing. This is nothing to do with connection to cloud but I'm not even getting pass that for Studios.
