Thanks Again...
I have bene able to find the root cause of my issue.
The intermediate/Root chain is not properly imported.
See the original setup, :
And now see the faulty, cloned setup:
But the question remains, how do I import just intermediate and root certificate which I have copied from original setup .
My question is, How can I import my intermediate and root certs in key storage? which option to selecct.
Maybe a silly qs but I need your help 
Thanks,
Rakesh
