Nginx конфигурация подключения Node js

Приветствую. Написал конфигурацию для nginx, клиент, который написан на React отображается, а вот Node не подключяется, ибо то что написал на ноде в клиент запрос не идет. Nginx перезагружал каждый раз, результата нет.

Nginx config:

      server {
          listen 80;
        
          location / {
                root /var/www/Website-LF-Frontend/build;
                index  index.html index.htm;
                proxy_http_version 1.1;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection 'upgrade';
                proxy_set_header Host $host;
                proxy_cache_bypass $http_upgrade;
                try_files $uri $uri/ /index.html;
          }
        
        location /matchesSlider {
                proxy_pass http://34.125.7.96:8888;
                proxy_http_version 1.1;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection 'upgrade';
                proxy_set_header Host $host;
                proxy_cache_bypass $http_upgrade;
          }
        }

Отрывок запроса в node:

app.get('/matchesSlider', (req, res) => {
    res.send(matchesSlider);
});
