VMware Cloud Director uses SSL to secure communications between clients and servers. Each VMware Cloud Director server must support an SSL endpoint for HTTPS communication.
Starting with VMware Cloud Director 10.4, both the console proxy traffic and HTTPS communications go over the default 443 port. You do not need a separate certificate for the console proxy.
Note:
VMware Cloud Director 10.4.1 and later do not support the legacy implementation of the console proxy feature.
