Nginx + SSL problem for old browsers

It's possible. 
But you should be able to tell on the client itself - if there is ssl cert domain mismatch or the client can't connect at all.

Imo the easiest way to check https://www.ssllabs.com/ssltest/ 

p.s. newer Openssl (1.1.x) versions by default disable weak ciphers. So depending on how your nginx/openssl is compiled the actual cipher list might be different to the configuration line.
