Why my Docker Certboot container stopped? Exit status 1

Question

My docker-compose.yml

version: "3.3"
services:
  proxy:
    image: nginx:stable-alpine
    restart: always
    ports:
      - "80:80"
      - "443:443"
    volumes:
      - ./sites-enabled:/etc/nginx/conf.d
      - ./proxy/logs:/var/log/nginx
      - ./certbot/www:/var/www/certbot
      - ./certbot/conf/:/etc/nginx/ssl
  certbot:
    image: docker.io/certbot/certbot:latest
    volumes:
      - ./certbot/www:/var/www/certbot
      - ./certbot/conf/:/etc/letsencrypt

After the restart

      Name                     Command               State                                    Ports                                 
------------------------------------------------------------------------------------------------------------------------------------
ingress_certbot_1   certbot                          Exit 1                                                                         
ingress_proxy_1     /docker-entrypoint.sh ngin ...   Up       0.0.0.0:443->443/tcp,:::443->443/tcp, 0.0.0.0:80->80/tcp,:::80->80/tcp

This what showed on screen

certbot_1  | Saving debug log to /var/log/letsencrypt/letsencrypt.log
certbot_1  | Certbot doesn't know how to automatically configure the web server on this system.

This is the output of the tree command

It seems that something wrong with path trajectory,regarding volume mounts.

How to find out what went wrong?
