If you have a customized SSL/TLS configuration in the registry.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols
Try the following config change to disable SSL to rule that out as the cause of the issue.
Stop QueryEngine and DataEngine services on and modify the following files.
In the C:\Program Files\Dell\UCCS Analytics\Query Engine\config directory locate and make a backup copy of the doradus.yaml
Open with notepad and find RESTService: section,
In this section change
tls: true
to
tls: false
Then in the in the C:\Program Files\Dell\UCCS Analytics\Data Engine directory locate and make a backup copy of Dell.UC.Insights.DataEngine.DoradusClient.dll.config,
In the following line:
<add key="UseHttps" value="True" />
change True to False
<add key="UseHttps" value="False" />
Start the services, If the install continues the issue is your SSL\TLS configruation.
Note: these settings are not meant for a production deployment just to help identify if SSL\TLS is the cause of the issue.
Review the following Microsoft Article for more details on configuring SSL.

If above does not work we require SHA to be enabled [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Hashes\SHA]
"Enabled"=dword:00000000
This registry key refers to Secure Hash Algorithm (SHA-1), as specified in FIPS 180-1. Its implementation in the Rsabase.dll and Rsaenh.dll files is validated under the FIPS 140-1 Cryptographic Module Validation Program.
To allow this hashing algorithm, change the DWORD value data of the Enabled value to the default value 0xffffffff. Otherwise, change the DWORD value data to 0x0.
