This is definitively too outdated for today's standards, tls 1.0 and 1.1 are out of the game .
You could try guys with these:

ssl_certificate /somepath/fullchain.cer;
ssl_certificate_key  /somepath/key.key;
ssl_trusted_certificate  /somepath/ca.cer;

ssl_session_timeout 1d;
ssl_session_cache shared:MozSSL:10m;  # about 40000 sessions
ssl_session_tickets off;
ssl_protocols TLSv1.2 TLSv1.3;
