Session Failure

[Maha]

Hi,

Just installed the latest CMN and connected my Z6 to the computer and started CMN.
I selected Nikon Z6 in the Connection drop down list and clicked on Connect.
Nothing happened.
started debugging and in the command stack I can read that the first command fails:

0 CONNECT (ASAP, Nikon Z6, 58ms (Error: 142 Session Failure)
1 ...
2 ...
3 TERMINATED_THREAD (ASAP)

What is the problem?
