When attempting to connect to a vCenter Server, an administrator observes the following at the top of the vSphere Web Client:
Could not connect to one or more vCenter Server Systems:https://vCenter.corp.com:443/sdk
What three reasons could be preventing the vSphere Web Client from communicating with this vCenter Server? (Choose three.)
A. The vCenter Server machine is not responding via the network.
B. An incorrect entry for this vCenter Server exists in the Single Sign-On service.
C. The SSL certificates do not match the FQDN address for the server.
D. The Platform Services Controller is external to this vCenter Server.
E. The DNS entry for the vCenter Server is incorrect.
Correct Answer: ABC
Explanation/Reference:
Explanation: This issue occurs in these situations:
During the re-installation of vCenter Server, it is possible to have the same vCenter Server registered more than once to Single Sign-On (SSO). With a previous install of vCenter Server, SSL certificates are not overwritten or removed properly during an upgrade or re-installation.
Note: If there are previous issues with the certificates, they may not be exposed until the installation and use of the 5.1 Web Client.
Before proceeding with the steps in the Resolution section, ensure that you are not experiencing the issue identified in vSphere Web Client 5.1 reports this SSL warning after an installation or upgrade: Failed to verify the SSL certificate for one or more vCenter Server Systems (2036505).
