Hello,
I'm ugins recommanded ciphers for nginx and Google Merchant bot can't connect :

Google Merchant can't negociate the TLS 1.2 connection,

Alert Message
With cipher list frop cipherli.st the server uses
TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 (0xc030) with ec_point_formats extension
and the TLS connexion works.
The connexion works with this home made cipher list :
ssl_ciphers
"ECDHE+aRSA+SHA384:EDH+CAMELLIA:EDH+aRSA:EECDH+aRSA+AESGCM:aRSA+SHA256:EECDH:ECDHE:+CAMELLIA128:+AES128:+SSLv3:!aNULL:!eNULL:!LOW:!3DES:!MD5:!EXP:!PSK:!DSS:!RC4:!SEED:!IDEA:!ECDSA:kEDH:CAMELLIA128-SHA:AES128-SHA";
I've added ECDHE+aRSA+SHA384 at start
Frédéric.
