reverse proxy -- showing directory index

[bruce <badouglas@xxxxxxxxx>]

Hi.

I'm testing out a github site. I had posted most of this awhile ago,
and it had appears to work. However, something is amiss/screwing up on
my part. In other words, FUBAR!

Instead of getting the site content, getting the directory index.


The test app:
 https://github.com/berat/waitlist-landing-page
 It's a node app that I'm running -- http://127.0.0.1:3000
 and using "pm2" and reverse proxy with apache2 to serve the page.

 The test url is -->> http://161.35.5.174/berat (if it were to work,
as it did for a bit)

The docroot
 /var/www/html/berat

config file
 /etc/apache2/berat.conf
 cat berat.conf

<VirtualHost *:80>
    ServerAdmin foo@xxxxxxxxx
    ServerName  temp22
    ServerAlias temp

    DocumentRoot   /var/www/html/berat

 RewriteEngine On

     ProxyPass /berat http://127.0.0.1:3000
     ProxyPassReverse /berat http://127.0.0.1:3000

 RewriteEngine On

    SetOutputFilter INFLATE;proxy-html;SUBSTITUTE;DEFLATE;
    ProxyHTMLInterp On
    ProxyHTMLExtended Off


      AddOutputFilterByType SUBSTITUTE text/html
      Substitute "s|/_next/static/|\.\./\.next/static/|"

      Substitute
"s|/_next/image\?url=\%2Fhero.jpg\&amp;w=1920\&amp;q=75|\.\./public/hero1|i"


    <Directory    /var/www/html/berat>

  Header Set Pragma "no-cache"
  Header Set Expires "Thu, 1 Jan 1970 00:00:00 GMT"
  Header Set Cache-Control "max-age=0, no-store, no-cache, must-revalidate"
  Header Unset ETag
  FileETag None

            Options +FollowSymLinks   +MultiViews
            AllowOverride All

            #use for 2.4?
            Require all granted

    </Directory>

    LogLevel debug
    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

for the above berat.conf file, I tested the following as well

     ProxyPass /berat/ http://127.0.0.1:3000/
     ProxyPassReverse /berat/ http://127.0.0.1:3000/

     ProxyPass /berat/ http://127.0.0.1:3000/
     ProxyPassReverse /berat http://127.0.0.1:3000

     ProxyPass "/berat" http://127.0.0.1:3000";
     ProxyPassReverse "/berat" http://127.0.0.1:3000";

     ProxyPass "/berat/" http://127.0.0.1:3000/";
     ProxyPassReverse "/berat/" http://127.0.0.1:3000/";

     ProxyPass "/berat/" http://127.0.0.1:3000/";
     ProxyPassReverse "/berat" http://127.0.0.1:3000";

     ProxyPass / http://127.0.0.1:3000
     ProxyPassReverse / http://127.0.0.1:3000

the process was
 a2dissite berat
 a2ensite berat

 systemctl reload apache2

 at the same time, from the /var/www/html/berat
  the "pm2" is stopped/restarted

  "stop"
  rm -rf /root/.pm2
  ls -al /root/.pm2
  pkill -f PM2
  ps -aux | grep -i "PM2"

  "restart"
    sudo -u www-data pm2 start npm --name "waitlist-landing-page" -- start
    curl http://127.0.0.1:3000

 at this point, the "pm2" server is generating the content, which
should be displayed via apache/server


Any/all pointers (frank!!) will be tested.

For the life of me, I can't seem to get this to work. I've
looked/rechecked the past email threads, but I'm still missing
something.

ps. The test process is running on a throwaway digitalocean instacne/ubuntu.

thanks
