Nginx configure SSL error "ERR_SSL_VERSION_OR_CIPHER_MISMATCH" - ssl

Question

I configure my nginx for a https service, but it does not work. The chrome showed error "ERR_SSL_VERSION_OR_CIPHER_MISMATCH". It's seemed like that the browser want an ssl protocol that my nginx can't support? However, I followed the official document from where I got the CA to configure my nginx.conf file as below.
I run curl https://ltp-cloud.com and get error "curl: (35) error:14077410:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure"
There is my nginx.conf:
```
user www-data;
worker_processes 4;
pid /var/run/nginx.pid;
events {
worker_connections 768;
# multi_accept on;
}
http {
server {
listen 443;
server_name ltp-cloud.com;
ssl on;
root html;
index index.html index.htm;
ssl_certificate /etc/nginx/ssl/cert/214234087720826.pem;
ssl_certificate_key /etc/nginx/ssl/cert/214234087720826.key;
ssl_session_timeout 5m;
ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_prefer_server_ciphers on;
location / {
root html;
index index.html index.htm;
}
}
}
My Nginx version is below and I checked that "--with-http_ssl_module" option is on.
