The following error occured on the client side even though the license manager on the server was working properly.
This error suggests that the client can't communicate with the server where the license manager is running.
There can be a few reasons for this error:
hosts file on the client and the server - make sure they include the correct IP address and hostname of the client and the server. Details.
The ARTWORK_LICENSE_FILE variable needs to be set properly. Details.
Define a specific port number for the license manager and the daemon and make sure to open these two ports on your firewall on the client and the server. Details.
