Error 500: Untrusted certificate
Your application is unable to connect to Data Refinery.
You receive an error message similar to this one:
Error 500: javax.net.ssl.SSLHandshakeException: com.ibm.jsse2.util.h: PKIX path building failed: java.security.cert.CertPathBuilderException: PKIXCertPathBuilderImpl could not build a valid CertPath.; internal cause is: java.security.cert.CertPathValidatorException: The certificate issued by CN=DigiCert Global Root G2, OU=www.digicert.com, O=DigiCert Inc, C=US is not trusted;
Why it's happening
Data Refinery is using SSL with a certificate from DigiCert. That certificate uses the SHA256 signature algorithm. But your truststore (whether provided by an IBM Cloud application container or not) doesn't contain DigiCert's SHA256 CA certificate.
How to fix it
To resolve this problem, get DigiCert's SHA256 CA certificate and configure it in your app or environment.
