Issue
Some web service providers may require mutual authentication and reject requests made without mutual authentication.
Symptoms
- Outbound web services from a ServiceNow instance are unable to communicate with a web service provider that requires mutual authentication.
- Web service authentication fails after configuring SAML with a different keystore.
Cause
Mutual authentication must be configured on the ServiceNow instance.
Resolution
Configure the mutual authentication properties on your ServiceNow instance. Details about setting these properties are available in the product documentation: Outbound SOAP mutual authentication.
