It’s possible that the issue is related to certificates, as you mentioned. When a client computer requests a license from a server, the server will authenticate the client’s identity by checking its certificate. If the certificate is not recognized by the server or if the client does not have a valid certificate, the server will deny the license request.

To give the ANSYS application a certificate signed by a different certification authority, you would need to generate a certificate request on the ANSYS license server and submit it to your certification authority for signing. Once you receive the signed certificate, you can install it on the ANSYS squidward license server and configure the ANSYS application to use it for client authentication.

Here are the general steps for obtaining and installing a signed certificate:


  1. Generate a certificate request on the ANSYS license server. You can use a tool like OpenSSL to generate the request. The request should include the server’s hostname and any other required information.

  2. Submit the certificate request to your certification authority for signing. Follow your certification authority’s instructions for submitting certificate requests.

  3. Obtain the signed certificate from your certification authority.

  4. Install the signed certificate on the ANSYS license server. This will involve importing the certificate into the server’s certificate store and configuring the server to use it for SSL/TLS communication.

  5. Configure the ANSYS application to use the new certificate for client authentication. This will involve updating the application’s configuration files with the new certificate’s thumbprint or other identifying information.


Once these steps are completed, clients should be able to request licenses from the ANSYS server using the newly-signed certificate. Make sure to test the new configuration thoroughly to ensure that all clients are able to obtain licenses correctly.
