sudo systemctl stop apache2.service
sudo apachectl restart
Seems there are two apache versions.
Still haven't fixed the certbot/lets encrypt registering the old cert. i'll have to address that problem when the cert expires in 1 month. If anyone has knowledge of certbot/lets encrypt, and the install on an AWS EC2 Bitnami wordpress. The old key is linked when attempting a renew even though a new key is installed and currently being vhosted.
