Thanks for the tip. I am running on Ubunto 14.04, which does not have a /etc/httpd/conf.d/ssl.conf file. However, I did a find for ssl.conf. Of the nine files returned, this is the only one which references port 443:

/opt/eff.org/certbot/venv/lib/python2.7/site-packages/certbot_apache/tests/testdata/centos7_apache/apache/httpd/conf.d/ssl.conf

Reference:
# When we also provide SSL we have to listen to the
# the HTTPS port in addition.
#
Listen 443 https

I don't know if this has anything to do with the issue because I am running on Unbuntu and not Centos. Even if it does, I don't know what to do about it other than rem out the Listen 443 https line.

Could all this have something to do with Let's Encrypt?

If interested, this is the link to a portion of my httpd-vhosts.conf file which shows the SSL setting for the Sentora control panel as well as two domains that had been configured with SSL -- http://rstunlimited.com/httpd-vhosts.pdf.

This should have nothing to do with Lets Encrypt. You should not need to comment out the Listen 443 in the httpd-vhosts.conf as that is the proper location for it. What the problem seems to be is that there is another Listen 443 being called somewhere else for some other reason. I use Ubuntu and I know the Sentora default configurations do not have Listen 443 anywhere. You need to make sure /etc/sentora/configs/apache/httpd.conf does not have Listen 443, also make sure /etc/apache2/apache2.conf looks like this:

Code:

# 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.

Good one, TGates! Replacing /etc/apache2/apache2.conf might be the answer. Mine has:
<IfModule mod_ssl.c>
Listen 443
</IfModule>
at the end, after the Include /etc/sentora/configs/apache/httpd.conf line. Wonder where it came from. I will copy your version, but might have to wait until September 1 to see if it fixed the problem, since that is when it usually blows out because Listen 443 gets added to the /etc/sentora/configs/apache/httpd.conf file the first of each month.

TGates · 08-17-2018, 06:57 AM

Nothing should be added to the httpd.conf... There is nothing in Sentora that touches that file. Only the httpd-vhosts.conf

As I had said, I replaced my version of /etc/apache2/apache2.conf with the one you provided, and it worked until this morning.

I am running on DreamCompute from DreamHost. I don't know if the server rebooted or what, but suddenly none of my three ssl domains could be accessed. Thinking perhaps DreamCompute has a special version of the conf file I copied the original apache2.conf back over to /etc/apache2/apache2.conf, and remmed out the line "Listen 443" .

However, that didn't work either. It wasn't until the Listen line was unremmed that the ssl domains would come up again. I don't know why the new version of apache2.conf worked at first, but now I'll be back to the first on the month problem as before. Below is my original version of /etc/apache2/apache2.conf.

By the way, what is the command to see where Listen 443 is active?

I agree that it shouldn't be there. But I just remmed out those three lines, and an ssl domain would not come up! For some reason, it appears to be necessary, at least until we get to the bottome of this mess.

Non of those should be loading, so I don't think that is the problem. If you rem out the one in the httpd.conf and un-rem the one in the httpd-vhosts.conf it should still work (that's how it is designed.)

This is what I did:
/etc/sentora/configs/apache/httpd.conf
no reference to 443

/etc/apache2/apache2.conf
rem out line referencing 443

/etc/sentora/configs/apache/httpd-vhosts.conf
unrem 443

Restarted apache2 -- so far, so good at bringing up ssl domains!
