CTGKS0070E Client authentication fails because server does not trust the client certificate. Check the logs for more information. Fix the problem and restart the server.

  Explanation Client
authentication fails because the server does not trust the certificate sent by the client. This
error can happen only if clientAuthentication is set to 2 (required) in the
SKLMConfig.properties file for key server. Note that for the KMIP protocol,
clientAuthentication is always set to required. 

  System action TLS handshake
fails and TLS connection cannot be established. 

  Administrator response
The certificate is not trusted by the server. Use the Pending Client Certificate REST
Service to list the pending client certificates and the Pending Client
Certificate Accept REST Service to accept the client certificates. Also, refer to the logs
for more information. Correct the problem and restart the server.
