An error message saying "Unable to connect to license manager"  means that your CLC Workbench is unable to make contact with the CLC Network License Manager (previously known as CLC License Server) that it has been configured to contact to obtain a license from.

This problem could be due to
  • misconfiguration of the Network License Manager information in the CLC Workbench, or
  • a connection problem between your Workbench and the Network License Manager, or
  • the Network License Manager is not contactable for other reasons, for example, the service may be down for some reason.
The Network License Manager information is configured in the Workbench as described in the manual section on setting up licensing:

https://resources.qiagenbioinformatics.com/manuals/clcgenomicsworkbench/current/index.php?manual=Configure_license_manager_connection.html

If that information is correct, then you will need to contact the administrator of your Network License Manager at your site and let them know you are experiencing this problem.

If they say the Network License Manager is running fine from their end and that other users can connect to it, then please check your own machine and Workbench settings to ensure that the Workbench can connect to your Network License Manager. For example, if there is a proxy set up at your site and it could affect your connection to the server running the Network License Manager software, please check your proxy settings for your machine and also check your Workbench proxy settings. The Workbench proxy settings are described in our manual here:
