Details

vSphere Client is enabled with all three protocols TLSv1.0,TLSv1.1,TLSv1.2 by default. If TLSv1.1, TLSv1.2 is enabled, you might get an error message while connecting the vCenter Server or ESXi using the vSphere Client.

Solution

Microsoft updates are required to make vSphere Client function with TLSv1.2 enabled ESXi or vCenter Server. 
To update, perform the steps below: 
  1. Navigate to the configuration file C:\Program Files (x86)\VMware\Infrastructure\Virtual Infrastructure  Client\Launcher\VpxClient.exe.config 
  2. Edit the VpxClient.exe.config file by setting the parameters   
  3. <add key = "EnableTLS12" value =  "false" /> as
    <add key = "EnableTLS12" value =  "true" />
     

  1. Connect using vSphere Client.

    Note: An error window will be displayed with an error similar to this:

    The requested security protocol is not supported.




  2. Install all Microsoft Windows Updates   
  3. Install all the KBs from https://www.microsoft.com/en-us/download/details.aspx?id=42334 which are required for Microsoft .Net 4.6.2 
  4. Install Microsoft .NET 4.6.2  
  5. Install the  KB related to TLS support for your operating system.

The user can successfully use vSphere Client to connect to vCenter Server or ESXi.
