Answer 1

It's difficult to diagnose without knowing more about your scenario, but you might want to experiment with the following setting that can be used in client config to bypass the certificate validation process:

        <serviceCertificate>
          <authentication certificateValidationMode="None"
                          revocationMode="NoCheck" />
        </serviceCertificate>
