Hi @jawaharyuvr ,
To me this looks like a certificate access issue. Here are a few things to check:
Is the path to the file correct? Does the user that your app is running as have read permissions on the directory & file where the cert is stored? Is the file a valid x509 cert? (Some commands here that can help with that: openssl - How do I view the details of a digital certificate .cer file? - Server Fault ) Verify that the password is correct for the key. You can do that with openssl as well . It should be something like this openssl rsa -in /path/to/private/key -check Hope that helps!
