apache question??

Hi Rob.

Thanks for the reply.

Have two/2 test ubuntu servers - digital ocean.

1st server contains the initial list of webapps to test.
Apps reside in /var/www/html/...
Apps have
 chown www-data:www-data
 chmod 755

The tgt app
 /var/www/html/berat

The vhosts reside
 /etc/apache2/sites-available
 berat.conf

The 2nd test srvr is a "clone" of the 1st. So the action/webapps
should run the same.

However, running into a weird issue.

The test "berat" uses a reverse proxy with a node app, to generate
content for the app.
When the node server isn't running, the app should display an err.

test srvr1

http://161.35.5.174/berat/
Index of /berat

.

the dir listing, instead of the "err" statement


-from the 2nd server
http://198.211.116.12/berat
The server is temporarily unable to service your request due to
maintenance downtime or capacity problems. Please try again later.

the working srvr...

test srvr2


Initially I ran both tests from the "/var/www/html/berat" dir.

But due to the issue with having the "dir" index/listing, I started
trying to figure out why.

I copied/tested the 1st srvr to the /var/www/html2/berat, changing the
berat.conf vhost for the docroot/directory as a test process.

No diff, still get the dir ndx/listing.

At this point, took a closer look at the err log
  tail -50 /var/log/apache/error.log

And I see a diff. -- don't know why, or what it means::

tst srvr1: --err
