How to correctly set the NGINX host (esc container)?

Question

Nginx

I need help with the config.
There is a project with 4 containers frontend, api and 2
nginx
.

[emerg] 1#1: host not found in upstream "frontend" in /etc/nginx/conf.d/default.conf:63

proxy_pass http://frontend:3000;
proxy_pass http://api:3000;
On the local machine I run
ngnix-forontend like this

server {
      listen         80;  // на сервере открыт только 443
      server_name    default localhost nginx-frontend frontend;
      return         301 https://$server_name$request_uri;
}

server {
    listen                    443;
    server_name               default localhost nginx-frontend frontend;
