Unlike vCenter, vROPS uses a common name vc-ops-slice-1 followed by slice-2 for data and other node, where vCenter has SAN names in the default certificate so when you add the root of the local machine trusted store then the vCenter url shows secured. In order to make the secure SSL we have to generate the CSR and get it signed by any third party SSL vendors or our own Microsoft CA.  I will be generating a CSR and getting signed by internal Microsoft CA .We can refer this below article from VMware as reference.  https://kb.vmware.com/s/article/2046591?lang=en_us Steps:  1.The first step is to create a new private key from taking a SSH session to master node vROPS. openssl genrsa -out vrops.key 2048 2.

I have attached a screenshot below. nameserver DNSIPAddress1 nameserver DNSIPAddress1 Quit out of the file, and perform a reboot. Workaround 2: Navigated to the file: /etc/systemd/netwo...
