Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is:
bookstack.quantox.dev

I ran this command:
docker-compose run --rm certbot -v certonly --webroot --webroot-path /var/www/certbot/ -d bookstack.quantox.dev
It produced this output:

It looks like the webserver you have running in your docker-compose set up, did not start properly.

Either that, or your domain is not pointing to the right server.

I am not sure about that. I am running this server on AWS Ec2 Instance. How to check if domain is not pointing to the right or wring server?

You could run curl ifconfig.me and confirm that the output is 18.158.222.31.

If the IP address is correct, then check that nginx is running before you run certbot, and that port 80 on the nginx container is being exposed to the host.

I checked all that. This is part of the docker-compose file
webserver:
image: nginx:alpine
container_name: webserver
restart: unless-stopped
tty: true
ports:
- "443:443"
- "80:80"
volumes:
- ./:/var/www
- ./nginx/conf.d/:/etc/nginx/conf.d/
- ./certbot/www:/var/www/certbot
- ./certbot/conf/:/etc/letsencrypt

Is the webserver container running right now? I can't access it.

certbot:
image: docker.io/certbot/certbot:latest
volumes:
- ./certbot/www:/var/www/certbot
- ./certbot/conf/:/etc/letsencrypt

I will double check and will respond soon.

Note that I'm not a docker expert, but shouldn't the certbot docker command also have some volume options? For the /var/www/certbot/ path as wel as for /etc/letsencrypt/, so the certificates will be saved persistently instead of ephemeral?
