-t says line of ssl_cipher has some issues (basically i had copied the above mentioned ciphers to my ssl.conf and post that nginx would not start)...
please remove the one on ssl.conf and place the ssl_cipher only on nginx.conf
Same error caused to me.
And I replace ssl_cipher with this one
and problem resolved.
