If you run the license manager and you get this error message:
Xlib: connection to "host_name" refused by server Xlib: Client is not authorized to connect to Server xhost: unable to open display "host_name"
it means the remote machine does not have permissions to display the user interface on the local machine where you are working.
To correct the problem, enter the following command at the UNIX prompt of your local machine:
xhost +remote_machine
where remote_machine is the machine on which you are running the license manager.Restart the license manager.
