A web client cannot be opened because of this error:

[400] An error occurred while sending an authentication request to the vCenter Single Sign-On server - An error occurred when processing the metadata during vCenter Single Sign-On setup - java.lang.IllegalArgumentException: no SSLSocketFactory specified.

Cause

This is a DNS issue. Try pinging the ESXi host by name. If you receive no response, ensure that there is a DNS host entry for your ESXi node.

Resolution

Place a host entry of the ESXi server in your DNS or local desktop hosts file.
Location:

C:\Windows\System32\drivers\etc\hosts

Like:

192.168.225.102 esxi2.testlab.com
192.168.225.103 esxi3.testlab.com

* Ensure that the time is synced between vCenter and VxRail manager.
