.well-known issue on Bitnami apache

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is: demo.bigopen.eu

I ran this command:sudo /tmp/certbot/certbot-auto certonly --webroot -w /opt/tomcat/apache-tomcat/webapps/ROOT/ -d demo.bigopen.eu

It produced this output:Saving debug log to /var/log/letsencrypt/letsencrypt.log

My web server is (include version): Apache Tomcat/8.0.38

The operating system my web server runs on is (include version):Ubuntu 14.04 LTS

My hosting provider, if applicable, is: Amazon EC2

I can login to a root shell on my machine (yes or no, or I don’t know):yes

I’m using a control panel to manage my site (no, or provide the name and version of the control panel):no

The problem seems to get for my browser (and for acme) anything from a “.well-known” subdir (acme-challenge in this case). If I manually put a file in another sibling “well-known” directory(without trailing dot) I can read it from my browser.
The weird thing is that I already succeedeed once, and the correct certs were generated and installed (thru webroot option). Now, at the time of renewing, I got this
strange behavior. The tricky policy of Bitnami Apache does not help.
Should I better ask the Bitnami people?
I already crawled thru this community but I could not find any similar case.
Thank you good willing men

I think that’s a good start. You can also share your apache configs here, and check for any “.htaccess” files that might be setting policies to not serve dotfiles.

dear jsha,
thank you for your reply.
I cannot find .htaccess files in the significant part of my file system (looking for -la option of course). Nonethe less I am ignorant about .htaccess usage.
Here is what is supposed to be the main .conf file in Bitnami realm, that is

# Default Virtual Host configuration.

I am aware that the
DocumentRoot "/opt/tomcat/apache2/htdocs"
is NOT the root dir under which I expect the .well-known stuff to be dropped, i.e.
but the latter is what is actually used by bitnami apache. I still can’t understand the way it works, but it works.

Any hint?

It seems like this (and the other includes) might be the key to your problem, along with the difference between /opt/tomcat/apache2/htdocs and /opt/tomcat/apache-tomcat/webapps/ROOT, as you point out.

I’d recommend trying the Apache plugin for certbot: certbot --apache.

Here are the includes:

$ cat apache2/conf/bitnami/bitnami-apps-prefix.conf

Bitnami applications installed in a prefix URL

Include “/opt/tomcat/apps/phpmyadmin/conf/httpd-prefix.conf”

$ cat /opt/tomcat/apps/phpmyadmin/conf/httpd-prefix.conf
Alias /phpmyadmin/ "/opt/tomcat/apps/phpmyadmin/htdocs/"
Alias /phpmyadmin “/opt/tomcat/apps/phpmyadmin/htdocs”

Include “/opt/tomcat/apps/phpmyadmin/conf/httpd-app.conf”

$ cat /opt/tomcat/apps/phpmyadmin/conf/httpd-app.conf

<Directory “/opt/tomcat/apps/phpmyadmin/htdocs”>

AuthType Basic

AuthName phpMyAdmin

AuthUserFile “/opt/tomcat/apache2/users”

<IfDefine USE_PHP_FPM>
   <FilesMatch \.php$>

ErrorDocument 403 “For security reasons, this URL is only accessible using localhost ( as the hostname.”

Include “/opt/tomcat/apps/phpmyadmin/conf/htaccess.conf”

$ cat /opt/tomcat/apps/phpmyadmin/conf/htaccess.conf
<Directory “/opt/tomcat/apps/phpmyadmin/htdocs/test”>

This folder does NOT need to be accessible over HTTP

In most cases the tests included here will be run from a command line interface.

(the following directive denies access by default)

For more information see: http://httpd.apache.org/docs/current/mod/mod_authz_host.html#allow

Order allow,deny


At this point, I got lost. Nothing seems to redirect from :

Did you miss this one?

Here’s to you (but it’s empty)

$ cat /opt/tomcat/apache2/conf/bitnami/bitnami-apps-vhosts.conf

Bitnami applications installed in a Virtual Host

first of all, I want to thank jmorahan and jsha for their precious support and help.
I overcame the problem observing in Tomcat Manager, a console I normally do not use, that the links to applications and services are originated under

and not under

So, I relaunched the certbot-auto with the --webroot option pointing to the correct root and it worked. (it just couldn’t flush the acme-challenge directory, but it wrote into it anyway)
Still don’t know the trick Bitnami uses to bounce the document root away, I will further investigate.
