带SSL(https)的webservices的Nginx设置

Nginx新手来了!我有以下伪代码:

<button onclick="myFunction()">Click me</button>
<p id="demo_id"></p>

<script>

function myFunction() 
{
    var loc = window.location;
    var wsStart = 'ws://';
    if (loc.protocol == 'https:') 
    {
        wsStart = 'wss://'
    }      

    var port =":8080" <!-- 
    var endpoint = wsStart + loc.host + port+'/personal/my_random_number/';

socket = new WebSocket(endpoint);

socket.onmessage = function(e) 
{
    document.getElementById("demo_id").innerHTML = e.data;
}

socket.onopen = function() 
{
    socket.send("hello world #");
} 

</script>

以及类似这样的nginx设置(ssl注释掉了):

server {
listen 80;
#listen 443 ssl;
server_name 157.200.0.100;

 #ssl_certificate /etc/letsencrypt/live/mydomain.com-0002/fullchain.pem;
 #ssl_certificate_key /etc/letsencrypt/live/mydomain.com-0002/privkey.pem;


# serve static files
location /static/ {
alias /www/static_3/;
}

# serve media files
location /media/ {
alias /www/media_3/;
}

location / {
proxy_pass http://$server_name:8080;
proxy_set_header X-Forwarded-Host $server_name;
}
}

#server {
#        listen 80;
#        server_name 157.200.0.100;
#        return 301 https://$host$request_uri;
#}

虽然web服务在http上工作得很好(不安全),但我不知道如何允许wss使用ssl(我注释掉了ssl设置,当我使用ssl设置时,站点工作正常,但wss不工作)。

问题: 如何“升级”我的nginx设置,让WS可以使用SSL?
