APM integration to SOI is not working and APM Connector log shows this error:
ERROR [CA:00001_xxxxxx@yyyyyy] connector.ApmConnector - APM Connector Initialize failed: (500)Internal Server Error.
If the connector has also been configured to trying to use SSL (EMWebserverProtocol=https) these errors may also be seen:
ERROR [CA:00001_xxxxxx@yyyyyy] connector.ApmConnector - APM Connector Initialize failed: ; nested exception is:
javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target.
