Am trying getting ssl certificate using letsencrypt and certbot with apache on my Ubuntu server for mydomain.com am getting the error using command sudo certbot --apache -d mydomain.com am getting error
The Certificate Authority failed to verify the temporary Apache configuration changes made by Certbot.
i tried tried to update sudo apt update then sudo apt install certbot and run again sudo certbot --apache -d mydomain.com still i got the same error.
i solved this by use the command
sudo certbot certonly --manual --preferred-challenges=dns -d mydomain.com
where by i added TXT records on dns configuration for verification and waited till i verified my records are saved via
https://toolbox.googleapps.com/apps/dig/#TXT/_acme-challenge.mydomain.com
do not forget to replace mydomain.com with you respect domain
