Required CA certificateSolved
We have used TurboActivate 3 for a long time, and are in the process of upgrading to TurboActivate 4.On some EC2 instances we are having a server connectivity issue. It appears that the issue might be related to the CA certificate. Please let us know what CA cert is required on the machine in order to connect to the licensing servers.Thanks!
