Client not authorized to connect to server

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.
