Floating error: -15

Floating error: -15 Cannot connect to license server system.

This licensing error occurs when our design tools cannot establish a connection to the FlexNet license manager.

Possible problems include:

  • If your are accessing from a different computer, check that the client machine has access to the license server. Verify that the firewall ports used by FlexLM are open between these computers.
    See this page: Ports used by FlexLM

  • Make sure The license manage port number is set to the correct port, by opening a browser where the FlexNet license manager is hosted and go to the Server Configuration Section;

    Administration > Server configuration > License server configuration
    

  • Configure your product license utility using the correct port no.
    Refer to Product license configuration for more details.

  • Check that your firewall is configured to allow the software to connect to the license manager.

  • Or disable firewall on your machines.

For Linux and MacOS

If Lumerical tools and FlexLM are running on the same machine.

  • Check that the host file is appended as:
$ sudo vi /etc/hosts
127.0.0.1  <machine_hostname> localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost6 localhost6.localdomain6
<your_machine_IP> <machine_hostname>
  • for example: computer name is linx_server and IP address is 192.168.1.100, your /etc/hosts would look like:
127.0.0.1  linx_server localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost6 localhost6.localdomain6 linx_server
192.168.1.100 linx_server
  • After changing the above file, restart FlexLM

    Note:
    The /etc/hosts file should also be updated whenever the HostName or IP address of the license server machine changes.
