I used a different method and thought I posted what I did.
However, I just installed the Bitnami LAMP instance on Lightsail and to the best of my knowledge did not install the Apache2 system services. Although, that might have happened during the LetsEncrypt install as that was the only thing installed beside making the changes to vhosts.
I used the following steps, however, it looks like I should use the steps you mentioned.
sudo pkill -f nginx
sudo pkill -f apache
sudo /opt/bitnami/ctlscript.sh start apache
My steps look temporary, so I will try the steps you mentioned.
Thank you for your time, knowledge, and assistance.
