Why does nginx from a Docker container not respond to certificates thrown into it?

Question

Nginx

Hey guys.
Please tell me how to diagnose the problem. Similarly to the specified tutorial https://medium.com/@marksta/this-was-so-useful-tha... I
registered a bunch of containers and launched the script for creating fake certificates. The only difference is in the nginx config (domen.ru - conditionally):

server {
    listen 80;
    server_name domen.ru;
    server_tokens off;
    root /public_html;

    location /.well-known/acme-challenge/ {
        root /var/www/certbot;
    }
}

server {
    listen 443 ssl;
    server_name domen.ru;
    server_tokens off;
    root /public_html;

    ssl_certificate /etc/letsencrypt/live/domen.ru/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/domen.ru/privkey.pem;
    include /etc/letsencrypt/options-ssl-nginx.conf;
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem;
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;

    location / {
        index index.html;
    }
}

docker-compose.yml :

version: '3'

services:
  nginx:
    image: nginx:1.15-alpine
    restart: unless-stopped
    volumes:
      - ./public_html:/public_html
      - ./data/nginx:/etc/nginx/conf.d
      - ./data/certbot/conf:/etc/letsencrypt
      - ./data/certbot/www:/var/www/certbot
    ports:
      - "80:80"
      - "443:443"
    command: "/bin/sh -c 'while :; do sleep 6h & wait $${!}; nginx -s reload; done & nginx -g \"daemon off;\"'"
  certbot:
    image: certbot/certbot
    restart: unless-stopped
    volumes:
      - ./data/certbot/conf:/etc/letsencrypt
      - ./data/certbot/www:/var/www/certbot
    entrypoint: "/bin/sh -c 'trap exit TERM; while :; do certbot renew; sleep 12h & wait $${!}; done;'"

With the following command, I make sure that the preferred certificates are:

docker exec nginx-certbot_nginx_1 ls /etc/letsencrypt/live/domen.ru;

cert.pem
chain.pem
fullchain.pem
privkey.pem
When launched from the project directory:
docker-compose up -d;
I am accessing https://domen.ru - https is crossed out.

Could this be a fake certificate? and sertbotovskie have not loaded yet?
When trying to renew the certificate:
docker exec nginx-certbot_certbot_1 certbot renew;

No renewals were attempted.
What could be wrong?
