Please make sure that you are appropriately setting the variable NODE_EXTRA_CA_CERTS in addition to updating the various settings to enable SSL in the server configuration file of the newer version of HC. Typically , the variable NODE_EXTRA_CA_CERTS is set via the batch file to launch the server. For example, in the file HOOPS_Communicator_202X\quick_start\start_server.bat, you can set the aforementioned variable like this:
@set NODE_EXTRA_CA_CERTS=D:/path/to/your/sslkeys/ca.pem
A separate forum post covering the topic of enabling SSL in Communicator is also available.
