issue

letsencrypt running fine, featured image in posts are showing, but all images are broken, because they are all having a http link.

solution

( by the OP kevc1973, based on the post in : https://bit.ly/3Pmg2SE )

  1. stop the service
sudo /opt/bitnami/ctlscript.sh stop
  1. backup the config file
/bitnami/ghost/config.production.json
  1. edit value of url the config file, replace http with https ;
    ( tried this before but resulted in some sort of localhost redirection, since i missed the followings );

  2. enable protocol proxy pass in apache
    config file :

/opt/bitnami/apps/letsencrypt/conf/httpd-app.conf

insert this line at the top of the config file :

RequestHeader set X-Forwarded-Proto "https"
  1. start the service
sudo /opt/bitnami/ctlscript.sh start

done ~
