Hi @johnnylegend.je, it would be great if you could share any output Apache throws when running the command below:
sudo /opt/bitnami/ctlscript.sh start apache
If not run this command:
sudo /opt/bitnami/apache2/bin/httpd -f /opt/bitnami/apache2/conf/httpd.conf -DFOREGROUND
It should keep running indefinitely, if it does so, try to access your site.
If it stops it should show an error. If this is the case, please share with us the contents of this command (right after the "sudo ..." one):
