After replacing {yourdomain.com} with actualy domain you can proxy requests to websocket

nginx-server.conf

map $http_upgrade $connection_upgrade {
  default upgrade;
  '' close;
}

upstream websocket {
  server 127.0.0.1:8000;
}

server {
  listen 80;
  listen 443 ssl http2;
  server_name {yourdomain.com};

  ssl_certificate /etc/letsencrypt/live/{yourdomain.com}/fullchain.pem;
  ssl_certificate_key /etc/letsencrypt/live/{yourdomain.com}/privkey.pem;
  ssl_trusted_certificate /etc/letsencrypt/live/{yourdomain.com}/chain.pem;
  ssl_protocols  TLSv1 TLSv1.1 TLSv1.2;
  ssl_ciphers HIGH:!aNULL:!eNULL:!EXPORT:!CAMELLIA:!DES:!MD5:!PSK:!RC4;
  ssl_prefer_server_ciphers on;
  ssl_session_cache shared:SSL:120m;
  ssl_buffer_size 4k;
  ssl_session_timeout 180m;
