setting up/running apache reverse proxy/PM2 node server

[bruce <badouglas@xxxxxxxxx>]

Hi, for those who have followed my attempts, thanks. This is a trimmed
down attempt.

Found some additional examples, and managed to get the following to
"work", once!

Not sure why it stopped, but I now get a 403/Fobidden err. error.log
inspection shows
/////
Cannot serve directory /var/www/html/berat/: No matching
DirectoryIndex (index.html,index.cgi,index.pl,index.php,index.xhtml,index.htm)
found, and server-generated directory index forbidden by Options
directive
////
Which is odd.. as the PM2 server doesn't create any of these file
types as far as I can tell.

I think I did a
  "systemctl stop apache2"
   "systemctl start apache2"
  to test
and after the "start", the 403 was displayed.

Here's the test vhost. The initial apache2.conf is the default with no changes.

The test site that has the 403 is
 http://161.35.5.174/berat

The working test site is..
http://198.211.116.12/berat

the berat_h.conf file is
<VirtualHost *:80>
    ServerAdmin foo@xxxxxxxxx
    ServerName  temp223a
    ServerAlias temp3a

# as test.. run from html2 berat_h
# all other apps are in html
# this is the same as the "clone" vhost

    #test for styles..
    #does order matter??? -- the actual ip is used to test..

            #use for 2.4?
            Require all granted

    </Directory>

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

OK.. WTH!!!!

Just retried the err srvr.. and the page is now showing...!!!
So something is happening that's not in the conf file?

Could it be some cache thing? Some node/PM2 thing? Some timing thing?
Something else??

I'm completely at a loss to explain this behaviour.

thanks
