openssl s_client -connect scouterecruitstaging.com:443 -ssl3
If you see a long response whereby the server certificate is shown, you do need to action.
If you see something like the next line, your server is fine:
58003:error:14094410:SSL routines:SSL3_READ_BYTES:sslv3 alert handshake failure
Find the file where ssl_protocols directive is:
cd /etc/nginx
grep -rin ssl_protocols .
Update from ssl_protocols SSLv2 SSLv3 TLSv1;
to ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
If you don't find any ssl_protocols, please add.
Restart nginx: sudo service nginx restart
Re-test with the first command.
