I am trying to install ssl certificate

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: tatjanajevdjic.design

I ran this command: sud certbot --apache

It produced this output:Saving debug log to /var/log/letsencrypt/letsencrypt.log
Plugins selected: Authenticator apache, Installer apache

Which names would you like to activate HTTPS for?

IMPORTANT NOTES:

My web server is (include version):Apache/2.4.29 (Ubuntu)

The operating system my web server runs on is (include version): ubuntu 18.04

My hosting provider, if applicable, is: digitalocean

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 version of my client is (e.g. output of certbot --version or certbot-auto --version if you’re using Certbot): certbot 0.31.0

This is telling you what the problem is–the Let’s Encrypt servers can’t connect to any of your hostnames on port 80. They need to be able to do that.

I would appreciate some directions - who am I supposed to ask - Digital Ocean or Hover regarding this issue? I am new to this, and I appreciate your help.
Thanks in advance,

Hi @tanjaj

it’s not a problem of your dns, that’s ok. You must have another blocking instance.

Only timeouts.

The two last rows are critical, because Certbot creates a validation file in /.well-known/acme-challenge, Letsencrypt checks that file.

            Configuration Overview
    </div>
    <div class="content_section_text">
      <p>
            Ubuntu's Apache2 default configuration is different from the
            upstream default configuration, and split into several files optimized for
            interaction with Ubuntu tools. The configuration system is
            <b>fully documented in
            /usr/share/doc/apache2/README.Debian.gz</b>. Refer to this for the full
            documentation. Documentation for the web server itself can be
            found by accessing the <a href="/manual">manual</a> if the <tt>apache2-doc</tt>
            package was installed on this server.

      </p>
      <p>
            The configuration layout for an Apache2 web server installation on Ubuntu systems is as follows:
      </p>
      <pre>

/etc/apache2/
|-- apache2.conf
| -- ports.conf |-- mods-enabled | |-- *.load |– *.conf
|-- conf-enabled
| -- *.conf |-- sites-enabled |– *.conf



  • apache2.conf is the main configuration
    file. It puts the pieces together by including all remaining configuration
    files when starting up the web server.
                    <li>
                       <tt>ports.conf</tt> is always included from the
                       main configuration file. It is used to determine the listening ports for
                       incoming connections, and this file can be customized anytime.
                    </li>

                    <li>
                       Configuration files in the <tt>mods-enabled/</tt>,
                       <tt>conf-enabled/</tt> and <tt>sites-enabled/</tt> directories contain
                       particular configuration snippets which manage modules, global configuration
                       fragments, or virtual host configurations, respectively.

So we know: Your webserver works internal. So it’s a firewall problem you have to fix.

There must be another blocking instance you have to found and change.

The online tool must be able to query your http version.

You’re right, I removed firewall (site was under construction)- and everything works fine.

Thank you very much for your help.
Now, I am sure about this stuff.

Best regards,
Tatjana
