I have 2 virtual hosts with 2 domains on 1 database running Ubuntu 16.04 on Apache2 LAMP stack.
My first domain www.benjaminthompson.org already has a certificate. My Postfix is encrypted aswell.
Now I want to encrypt my second domain www.a-c-d.net.
sudo add-apt-repository ppa:certbot/certbot
sudo apt-get update
sudo apt-get install python-certbot-apache
Client with the currently selected authenticator does not support any combination of challenges that will satisfy the CA.
How do I work around this to get a certificate on my second domain?
Any help will be greatly appreciated, thanks !!
