Type of issue

Current Behavior

In earlier versions of OPC Foundation framework the private keys where exportable but now it is not possible to export them. When I try to connect to an UA Server with a GDS certificate to X509 LocalComputer/UA Applications, generated by version 1.5.374.78, I get the error message : 10/16/2024 09:50:36.992 Trying to add certificate to cache with invalid private key. 10/16/2024 09:50:37.007 Trying to add certificate to cache with invalid private key. 10/16/2024 09:50:37.070 Unexpected error in '(null)'. BadConfigurationError 'Cannot access certificate private key. Subject=CN=xxxx, DC=yy.yy.yy.yyy'
