I am trying to study boulder(https://github.com/letsencrypt/boulder) in my machine. This is for studying Certificate Authority and boulder to be implemented for our current project in our company.
I am facing issue in getting certificate from boulder using certbot client. The below explains step by step procedures I did
1, Added hostname in /etc/hosts -> 0.0.0.0 www.example.com
2, Started boulder using sudo docker-compose up
3, sudo certbot certonly --standalone -d www.example.com --server http://localhost:4000/directory
After this I am getting below unauthorized error
Detail: The key authorization file from the server did not match
I tried changing FakeDNS address to 172.17.0.1(docker ip), which is causing connection refused error.
Please help me solve this case as I am new to certificate authority and boulder
