Question

Installed LetsEncrypt to get SSL and now my website is not reachable

Posted July 18, 2020 585 views
ApacheWordPressDigitalOceanLet's Encrypt

I am following this tutorial https://www.digitalocean.com/community/tutorials/how-to-secure-apache-with-let-s-encrypt-on-ubuntu-18-04 and after I followed the steps and went to my website it was gone. I tried to log into the WordPress admin panel and the webpage and got a 403 error. I realized I forgot to add domain.com (the .com part) so I repeated the steps. Now I get “Success! The your_domain virtual host is working!” when I go to domain.com, instead of my wordpress site I built. What happened to my website!?

I don’t know what to do help would be really appreciated.

Hi there @vinnyp96,

Can you share the content of your Apache virtual host? To do that you could first find the file with the following command

  • ls -lah /etc/apache2/sites-enabled

There you should see 2 files associated with your domain name, one for your SSL Vhost and one for the non-SSL Vhost.

Then use the cat command to display the content:

  • sudo cat /etc/apache2/sites-enabled/your-domain.conf

Feel free to share the output here.

Also please check your Apache error log with the following command:

  • sudo tail -100 /var/log/apache2/error.log

Regards,
Bobby

Hi @bobbyiliev I appreciate your help!

output to ls -lah /etc/apache2/sites-enabled:

error.log was empty.

Thanks!

    Hi there @vinnyp96,

    The Apache virtual host for port 80 actually looks correct.

    Can you share the contents of the SSL Vhost as well?

    • sudo cat /etc/apache2/sites-enabled/your-domain.com-le-ssl.conf

Hi @bobbyiliev,

root@XXX:~# sudo cat /etc/apache2/sites-enabled/<DOMAIN>.com-le-ssl.conf 
<IfModule mod_ssl.c>
<VirtualHost *:443>
    ServerAdmin webmaster@localhost    
    ServerName <DOMAIN>.com    
    ServerAlias www.<DOMAIN>.com    
    DocumentRoot /var/www/<DOMAIN>.com    
    ErrorLog ${APACHE_LOG_DIR}/error.log    
    CustomLog ${APACHE_LOG_DIR}/access.log combined

Include /etc/letsencrypt/options-ssl-apache.conf
SSLCertificateFile /etc/letsencrypt/live/<DOMAIN>.com/fullchain.pem
SSLCertificateKeyFile /etc/letsencrypt/live/<DOMAIN>.com/privkey.pem
</VirtualHost>
</IfModule>

Also to add on: going to www.<domain>.com I get:

Success! The your_domain virtual host is working!

Going to http://<IP>/wp-admin/ I used to be able to login to Wordpress and edit my site, now I get:

Not Found

The requested URL was not found on this server.

    Hi there @vinnyp96,

    Actually both the SSL and the non-SSL Vhosts look all correct. With a small exception, I would recommend adding the following to both your SSL and non-SSL virtual hosts:

    <Directory /var/www/yourdomain.com/>
    AllowOverride All
</Directory>

    This would basically allow the usage of the .htaccess file which is needed by WordPress.

    After the change, run a config test:

    • sudo apachectl -t

    And if you get a Syntax OK message, restart Apache:

    systemctl restart apache2

    If you are still seeing the problem, I could suggest a couple of things:

    • Make sure that the file permissions for the /var/www/yourdomain.com folder are set correctly so that Apache could read and write accordingly. You can take a look at this article here on how to set that up:

    https://www.digitalocean.com/community/tutorials/how-to-install-wordpress-with-lamp-on-ubuntu-18-04

    • Check the content of the /var/www/yourdomain.com folder and make sure that it actually holds the files of your WordPress website:
    • ls -lah /var/www/yourdomain.com
    • Also share the content of the 000-default.conf file just to make sure that there are no problems coming from there

    Regards,
    Bobby

    How To Install WordPress with LAMP on Ubuntu 18.04
    by Brian Boucheron
    WordPress is the most popular CMS (content management system) on the internet. It allows you to easily set up flexible blogs and websites on top of a MySQL backend with PHP processing. In this guide, we'll focus on getting a WordPress instance set up on a LAMP stack (Linux, Apache, MySQL, and PHP) on an Ubuntu 18.04 server.

      Hi @bobbyiliev,

      I added the 

      <Directory /var/www/yourdomain.com/>
    AllowOverride All
</Directory>

      and ran sudo apachectl -t. I got the output:

      # sudo apachectl -t

[Wed Jul 22 03:23:16.783007 2020] [core:warn] [pid 3099] AH00111: Config variable ${apache_log_dir} is not defined

The Apache error log may have more information.

      Inside /var/www/yourdomain.com:

      root@xxx:/var/www/<DOMAIN>.com# cat index.html 
<html>
    <head> 
        <title>Welcome to Your_domain!</title>    
    </head>    
    <body>        
        <h1>Success!  The your_domain virtual host is working!</h1>    
    </body>
</html>

      I made this as part of the original tutorial when I started this SSL tutorial. This is definitely not my wordpress site, I don’t know where on this droplet that would be located…

      content of the 000-default.conf:

        Hi there @vinnyp96,

        What I could suggest is to disable the Vhosts that you do not need and leave only the one that you need with the correct DocumentRoot path to your WordPress files.

        At the moment in your /var/www/<DOMAIN>.com directory, you just have a default inedx.html file rather than your actual WordPress installation.

        Let me know how it goes.
        Regards,
        Bobby

To add one going to www.domain.com all I see is
“Success! The your_domain virtual host is working!”

Before I tried adding SSL and did all these steps, going to http://IP-address/wp-admin/ resulted in a WordPress login page and then I could edit my website. Now I get:

Not Found

The requested URL was not found on this server.
