We are trying to consume a internal web service from Appian and it requires a certificate to be installed in Appian. Post the cert installation, we are able to discover the WSDL and the related operations. However, we get a 'Policy Falsified' error when we run the webservice node. We enabled webservice logging and extracted the outgoing request xml and tried it from SOAP UI and it Works fine.
Any idea what could be wrong here?
FYI - there is no authentication needed for this service other than the cert install.

<l7:policyResult xmlns:l7="www.layer7tech.com/.../fault" xmlns:l7p="www.layer7tech.com/.../policy" status="Assertion Falsified">
<l7:assertionResult assertion="l7p:SslAssertion" status="Authentication Required" />
<l7:assertionResult assertion="l7p:All" status="Authentication Required" />
<l7:assertionResult assertion="l7p:SslAssertion" status="Assertion Falsified">...
