My root ca and intermediate is Digicert and I downloaded them from here https://www.digicert.com/kb/digicert-root-certificates.htm#roots
https://www.digicert.com/kb/digicert-root-certificates.htm#intermediates

Verified chain -

openssl verify -CAfile DigiCertHighAssuranceEVRootCA.crt.pem -untrusted DigiCertSHA2HighAssuranceServerCA.crt.pem azara.crt 
domain.crt: OK

and my order is root -> intermediates -> server.crt passing this complete bundle in the configuration throwing error of invalid certificate chain. Is anything I am doing wrong here ?
