@andresrc Thanks man, that worked.
Also I have another question about step 5.
It says: Create a script at /etc/lego/renew-certificate.sh with the following content. Remember to replace the DOMAIN placeholder with your actual domain name, and the EMAIL-ADDRESS placeholder with your email address.
Does that mean I should log onto my FTP client, navigate to the /etc/lego/ folder (if so, where is this located at?) and then upload a file called renew-certificate.sh with the following content:
sudo /opt/bitnami/ctlscript.sh stop apache
sudo /usr/local/bin/lego --email="EMAIL-ADDRESS" --domains="DOMAIN" --path="/etc/lego" renew
sudo /opt/bitnami/ctlscript.sh start apache
Or does it mean I should just run these commands through the terminal command line?
