Unable to establish SSL connection when testing on the lastes version

[w0rld]

Hi, everyone, I used the lastest version code, but I still meet this error "Unable to establish SSL connection", could you please give some advise?
start nignx:
sudo LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:$(pwd)/../libressl-2.4.1/lib ./objs/nginx

However, the wget cannot establish SSl connection with nginx:

The nginx.conf:

server
{
       listen       7788 ssl;
       server_name  localhost;

       ssl_certificate      cert.crt;
       ssl_certificate_key  cert.key;

       ssl_session_cache    shared:SSL:1m;
       ssl_session_timeout  5m;

       ssl_ciphers  HIGH:!aNULL:!MD5;
       ssl_prefer_server_ciphers  on;

       location / {
           root   html;
           index  index.html index.htm;
       }
  }
