I had the issue that I was not able to install the latest CR15 of HCL Connections 8 in a customer environment using the GUI of the Installation Manager. I always received the following error message when validating the connection to the Deployment Manager:CLFRP0005E: Cannot get SSL certificate from the Deployment Manager.
