HestiaCP + jellyfin. Reverse proxy NGINX

I tried this for http:

It works for me.

server {
    listen      %ip%:%proxy_port%;
    server_name %domain%;

location / {
    proxy_pass      http://%ip%:8096;
    }
}

An example from Jellyfin documentation does not work. Why?

server {
      listen %proxy_port%;
      listen [::]:%proxy_port%;
      server_name %domain%;

      access_log /var/log/nginx/jellyfin.access;
      error_log /var/log/nginx/jellyfin.error;

      set $jellyfin %ip%;

      location / {
          proxy_pass http://%ip%:8096;
          proxy_set_header Host $host;
          proxy_set_header X-Real-IP $remote_addr;

          proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
          proxy_set_header X-Forwarded-Proto $scheme;
          proxy_set_header X-Forwarded-Protocol $scheme;
          proxy_set_header X-Forwarded-Host $http_host;

          # Disable buffering when the nginx proxy gets very resource heavy upon streaming
          proxy_buffering off;
      }

      # location block for /web - This is purely for aesthetics so /web/#!/ works instead of having to go to /web/index.html/#!/
      location ~ ^/web/$ {
          # Proxy main Jellyfin traffic
          proxy_pass http://$jellyfin:8096/web/index.html/;
          proxy_set_header Host $host;
          proxy_set_header X-Real-IP $remote_addr;
          proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
          proxy_set_header X-Forwarded-Proto $scheme;
          proxy_set_header X-Forwarded-Protocol $scheme;
          proxy_set_header X-Forwarded-Host $http_host;
      }

      location /socket {
          # Proxy Jellyfin Websockets traffic
          proxy_pass http://$%ip%:8096;
          proxy_http_version 1.1;
          proxy_set_header Upgrade $http_upgrade;
          proxy_set_header Connection "upgrade";
          proxy_set_header Host $host;
          proxy_set_header X-Real-IP $remote_addr;
          proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
          proxy_set_header X-Forwarded-Proto $scheme;
          proxy_set_header X-Forwarded-Protocol $scheme;
          proxy_set_header X-Forwarded-Host $http_host;
      }
