Dear All,
I have an issue with certificates. In our organization we have 2 environments like UK and US regions. I have a connectivity from IIBV9(Windows Server 2012 R2) to SSO (Single Sign On â€“ windows Server) in UK and US regions. Recently the SSO servers are updated with a new Digi Sign Certificate in UK and US Servers (Same Certificate). Now, if I test the existing services from IIB to SSO, the UK Services are working fine and the US Services are giving certificate chaining error. Both the IIB servers having same services with same functionality and earlier working fine in 2 regions. After updating the cert, in the US environment getting below error.
java.security.cert.CertPathBuilderException: PKIXCertPathBuilderImpl could not build a valid CertPath.; internal cause is:
java.security.cert.CertPathValidatorException: The certificate issued by CN=USERTrust RSA Certification Authority, O=The USERTRUST Network, L=Jersey City, ST=New Jersey, C=US is not trusted; internal cause is:
java.security.cert.CertPathValidatorException: Certificate chaining error

If I add the signer certificates to Broker trust store in US environment, I guess It will work. But my question is why without any changes the UK environment is working and US env is not? Please suggest.
