nginx添加ssl后无法访问，修改配置如下

server {
  listen  80;
  server_name xxx.abc.com;
  #ssl
  listen  443 ssl;
  ssl_certificate         /root/01-ssl_cert/xxx.xxx.com/cert.pem;
  ssl_certificate_key   /root/01-ssl_cert/xxx.xxx.com/cert.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;

  # api config
  location / {
    include   uwsgi_params;

    # Preflighted requests
