Another interesting fact that OpenSSL works on the same box 

# openssl s_client -tls1_2 -cipher ECDHE-RSA-AES128-GCM-SHA256 -connect services6.arcgis.com:443 -servername services6.arcgis.com

Adding a cert (generated by openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout client.key -out client.pem) as

proxy_ssl_certificate /etc/nginx/client.pem;
proxy_ssl_certificate_key /etc/nginx/client.key;

does not help as well.

Without -servername services6.arcgis.com, openssl fails with exactly the same error:

Clearly this is not an nginx issue, but rather backend server behaviour. Consider using ​proxy_ssl_server_name on; if your backend requires SNI.
