NGINX http to https if only contains certain directory - nginx

Question

I have been tasked with a couple project.
We have two directories on our server, one is
http://example.com/app
and the other is
http://example.com/fw
What I have been asked to do, is redirect from http to https if any visitor lands on a page in these two directories (app and fw)
Here is what I have done so far in the config file. When I added the lines to my config file below 'server' and restarted the site would not come back up. Unfortunately I don't have access to the log files. Appreciate anyone willing to take a look at this
location ~ ^/miner/memclub/.+\.html$ {
rewrite ^(.+)\.html$ /bootstrap.php?file=$1.html last;
rewrite ^(.+)\.phtml$ /bootstrap.php?file=$1.phtml last;
error_page 404 = /404.php;
}
server {
server_name site.org;
server_name *.site.org;
location /app {
if ( $scheme = http ) {
rewrite ^ https://site.org/app last;
}
}
}

First of all I don't think you can have 2 server_name, merge those two lines into one line
server_name example.com *.example.com;
And to do the https redirect i would recommend using 2 separate servers, you need one listening to port 443 anyway
server {
server_name example.com www.example.com; # which ever you are using
listen 443 ssl;
location / {
# all your https configuration
}
}
server {
server_name example.com www.example.com:
listen 80;
location /app {
return 301 https://$http_host$request_uri;
}
location /fw {
return 301 https://$http_host$request_uri;
}
location / {
# the rest of the non https configuration
}
}
I know you can merge both app and fw into one location, but I believe doing it without regex is faster, if you want to do it anyways here it is
location /(app|fw) {
return 301 https://$http_host$request_uri;
}
