I am not sure about the below explanation as seen in the above output.
Testing server preferences
Has server cipher order? no (NOT ok)
Negotiated protocol TLSv1.2
Negotiated cipher ECDHE-RSA-AES128-GCM-SHA256, 521 bit ECDH (P-521) -- inconclusive test, matching cipher in list missing, better see below
Negotiated cipher per proto (matching cipher in list missing)
ECDHE-RSA-AES256-GCM-SHA384: TLSv1.2
No further cipher order check has been done as order is determined by the client
I will appreciate if someone can help me understand it. Does it mean there is some issue? Thanks in advance and I look forward to hearing from you.
