Hello Team,

While establishing connection for https protocol , facing the issue with 
certification although ca bundle have cert required.
It's happening only in customer environment.  Whereas all test machines are 
able to successfully verify the certificate.

Root Certificate required is Entrust Root Certification Authority - G2 and it 
does present in CA bundle provided. CA Bundle used in both machines is same.
Is there any reason its failing only in specific environment though CA bundle 
is same?

Cert hierarchy:
