Error 'Application terminated prematurely' occurs on RHEL 7.6, due to SELinux enforcing policies

SELinux policies on Red Hat 7.6 deny some operations during the initialization of the NoMachine session (either a connection to the physical desktop or a virtual desktop) and prevent the session to start.

Users get error like:

The session negotiation failed. Error: Session failed, application terminated prematurely.

This problem occurs with NoMachine v. 5 and it's not present in NoMachine v.6 which provides a SELinux policy package suitable also for RHEL 7.6 policies. Upgrading to the last NoMachine version it's strongly suggested, whenever possible.
