There - the IPv4 uses RSA and gets A+ and the IPv6 uses ECDSA and gets A+
There is no chain issue.
But when I have both certificates - it appears to be doing right thing in client test (clients that support secp521r1 use ECDSA ciphers, others use aRSA ciphers) but the test complains about incomplete chain.
This is what I am doing to use both :
# ECDSA Certificate
# RSA Certificate
Right now in the linked test, the ECDSA are just commented out for IPv4 and the RSA are just commented out for IPv6 to demonstrate the chains are correct.
Is this a Qualys bug or am I not understanding how to do dual certificates?
