I am planning to setup lets encrypt HTTPS certificates for my applications which is deployed in tomcat. Also to note that this is my local environment and not exposed to public IP. Now when I am trying to create certificate with lets encrypt (certbot) I am getting error “Detail: DNS problem: NXDOMAIN looking up A for <abc.internal.com>”. Now can any one help me with the steps to install the same and setup in tomcat for the INTRANET.
Note: As my environment in INTRANET, so, DNS would not be accessible from outside world.
