hi @deepak36,
my case is very similar to yours, but my site can always do https, including the feature image, but all other images in the post body content will be shown in http. very strange.
i have followed the links provided by @MartinGross , and it did help ~
just that the path to “httpd-app.conf” should be :
/opt/bitnami/apps/letsencrypt/conf/httpd-app.conf
and it now works for me. hope this will also solve yours ~
my post asking for help in this issue :
