Nginx 配置求助，如何讲 wss 和 https 同时指向一个域名

server {
listen 443 ssl;
server_name ru.oxo-chat-server.com;
ssl_certificate /etc/letsencrypt/live/ru.oxo-chat-server.com/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/ru.oxo-chat-server.com/privkey.pem;
ssl_protocols TLSv1.2;
ssl_prefer_server_ciphers on;
ssl_ciphers EECDH+AESGCM:EDH+AESGCM:AES256+EECDH:AES256+EDH;
root /usr/share/nginx/html;
index index.html index.htm;

server_name localhost;

location / {
try_files /nonexistent @$http_upgrade;
}

location @websocket {
proxy_pass http://localhost:3000/;
proxy_http_version 1.1;

proxy_set_header Connection "upgrade";
proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;

}

location @ {

proxy_set_header X-Forward-Proto http;
proxy_set_header X-Nginx-Proxy true;
proxy_redirect off;
}
}

server {
listen 80;
server_name ru.oxo-chat-server.com;
return 301 https://$host$request_uri;
}
