Atelier and External Web Server

I have Caché/HealthShare installed in a local Ubuntu 16.04 LTS virtual machine. I've also installed Apache 2.4 from the apache2 bundle, and enabled SSL. I've configured Caché such that SSL/TLS is enabled on the SuperServer port but not required.

I had originally set up port 80 and the default site to redirect to SSL, then realized that Atelier doesn't (yet) support an SSL connection. So I created a second, non-SSL site on a different port that allows me to log into the management console without SSL either locally or from another VM (or the host operating system). However, when I configure that port number in Atelier, it complains "Not Found. Check the web server configurations."

I've tried reconfiguring port 80 such that it doesn't redirect to the SSL port, but get the same results (interestingly, with the redirect in place I get "Found" in red when I test the port, but Atelier won't actually connect).

The next step is to re-enable the "private" web server and see if that works. But I'm hoping that Atelier will work with the external server too.

I've backed out all of the changes that I would have suspected might have an impact, and it's still working (and yes, I've restarted both Apache and Caché). The only thing I haven't yet backed out was the creation of a non-SSL site  on port 8881, but that's something I did early on and am fairly certain I tried an Atelier connection after. But I may be misremembering ...

I'm getting a "Not Found" error.

Here's my apache2.conf:

# This is the main Apache server configuration file.  It contains the
# configuration directives that give the server its instructions.
# See http://httpd.apache.org/docs/2.4/ for detailed information about
# the directives and /usr/share/doc/apache2/README.Debian about Debian specific
# hints.
#
#
# Summary of how the Apache 2 configuration works in Debian:
# The Apache 2 web server configuration in Debian is quite different to
# upstream's suggested way to configure the web server. This is because Debian's
# default Apache2 installation attempts to make adding and removing modules,
# virtual hosts, and extra configuration directives as flexible as possible, in
# order to make automating the changes and administering the server as easy as
# possible.



# It is split into several files forming the configuration hierarchy outlined
# below, all located in the /etc/apache2/ directory:
#
#    /etc/apache2/
#    |-- apache2.conf
#    |    `--  ports.conf
#    |-- mods-enabled
#    |    |-- *.load
#    |    `-- *.conf
#    |-- conf-enabled
#    |    `-- *.conf
#     `-- sites-enabled
#         `-- *.conf
#
#
# * apache2.conf is the main configuration file (this file). It puts the pieces
#   together by including all remaining configuration files when starting up the
#   web server.
#
# * ports.conf is always included from the main configuration file. It is
#   supposed to determine listening ports for incoming connections which can be
#   customized anytime.
#
# * Configuration files in the mods-enabled/, conf-enabled/ and sites-enabled/
#   directories contain particular configuration snippets which manage modules,
#   global configuration fragments, or virtual host configurations,
#   respectively.
#
#   They are activated by symlinking available configuration files from their
#   respective *-available/ counterparts. These should be managed by using our
#   helpers a2enmod/a2dismod, a2ensite/a2dissite and a2enconf/a2disconf. See
#   their respective man pages for detailed information.
#
# * The binary is called apache2. Due to the use of environment variables, in
#   the default configuration, apache2 needs to be started/stopped with
#   /etc/init.d/apache2 or apache2ctl. Calling /usr/bin/apache2 directly will not
#   work with the default configuration.

So, I got it working.

It took a long time, because I missed one very important detail: the trailing backslash on the URL is very, very important. I was testing in my browser with http://oobuntoo.local:8881/api/atelier, which isn't exactly what Bernd and Dmitry told me to do. Since that wasn't working, I wasn't bothering to test Atelier's ability to connect. So somewhere in my flailing around I managed to fix whatever was preventing it from working, and now I need to backtrack through that and figure out what it was.

So ... thanks everyone. I'll mark the right answer as correct as soon as I figure out which one it was!
