Hello All,

Is it possible to know what certificates does the NPI connector end point URL (https://npiregistry.cms.hhs.gov/api/demo) uses?

When I initially downloaded the NPI connector from PEGA Exchange and established the connection I encountered certificate chaining error for VeriSign as below:

internal cause is:
java.security.cert.CertPathValidatorException: The certificate issued by CN=VeriSign Class 3 Public Primary Certification Authority - G5, OU="(c) 2006 VeriSign, Inc. - For authorized use only", OU=VeriSign Trust Network, O="VeriSign, Inc.", C=US is not trusted; internal cause is:
java.security.cert.CertPathValidatorException: Certificate chaining error

(NOTE: We fixed the above issue by adding the certificate to default truststore in websphere)

This morning when I was attempting to establish the connection I am getting certificate chaining error for Entrust as below:

internal cause is:
java.security.cert.CertPathValidatorException: The certificate issued by CN=Entrust Root Certification Authority, OU="(c) 2006 Entrust, Inc.", OU=www.entrust.net/CPS is incorporated by reference, O="Entrust, Inc.", C=US is not trusted; internal cause is:
java.security.cert.CertPathValidatorException: Certificate chaining error

Does the certificate change very often? If yes, is there any way to handle this situation?

Thank you in advance.
