Subdomains getting redirected to root directory of virtualhost

Question

I'm trying to have 3 different domains and subdomains on my VPS:

• pd.example.com
• intranet.example.com
• example.com

I have configured them, but for some reason each subdomain is getting redirected to the same index.html that is in the root directory of example.com

The screenshot for intranet.example.com:

The screenshot for example.com:

Here is the virtualhost for intranet.example.com:

<VirtualHost *:80>

    ServerAdmin soporte@example.com
    ServerName intranet.example.com
    ServerAlias www.intranet.example.com
    DocumentRoot "/var/www/intranet/"

    <Directory "/var/www/intranet/">

            Options Indexes FollowSymLinks
            AllowOverride all
            Require all granted

    </Directory>

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

    RewriteEngine on
    RewriteCond %{SERVER_NAME} =www.intranet.example.com [OR]
    RewriteCond %{SERVER_NAME} =intranet.example.com
    RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]
</VirtualHost>

Here is the virtualhost for example.com:

<VirtualHost *:80>

    ServerAdmin soporte@example.com
    ServerName example.com
    ServerAlias www.example.com
    DocumentRoot /var/www/example

    <Directory /var/www/example>

            Options Indexes FollowSymLinks
            AllowOverride all
            Require all granted

    </Directory>

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

    RewriteEngine on
    RewriteCond %{SERVER_NAME} =www.example.com [OR]
    RewriteCond %{SERVER_NAME} =example.com
    RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]
</VirtualHost>

Did I configure my virtualhosts correctly?

These are the 443 Virtual hosts for example.com:

    <IfModule mod_ssl.c>
    <VirtualHost *:443>

    ServerAdmin soporte@example.com
    ServerName example.com
    ServerAlias www.example.com
    DocumentRoot /var/www/example

    <Directory /var/www/example>

            Options Indexes FollowSymLinks
            AllowOverride all
            Require all granted

    </Directory>

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

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

This is for intranet.example.com:

    <IfModule mod_ssl.c>
    <VirtualHost *:443>

    ServerAdmin soporte@example.com
    ServerName intranet.example.com
    ServerAlias www.intranet.example.com
    DocumentRoot "/var/www/intranet/"

    <Directory "/var/www/intranet/">

            Options Indexes FollowSymLinks
            AllowOverride all
            Require all granted

    </Directory>

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

    Include /etc/letsencrypt/options-ssl-apache.conf
    SSLCertificateFile /etc/letsencrypt/live/www.intranet.example.com/fullchain.pem
    SSLCertificateKeyFile /etc/letsencrypt/live/www.intranet.lsgob.us/privkey.pem
    </VirtualHost>
    </IfModule>

.htaccess

    RewriteEngine On
    RewriteCond %{HTTP_HOST} !^www\.
    RewriteRule ^(.*)$ https://www.%{HTTP_HOST} [R=301,L]

As mentioned in comments, I don't see any spurious redirects that you appear to be reporting and the two URLs do appear to return different content (although they "look similar"). So this appears to show different index.html documents, not the same?

Not the cause of the current problem, but your redirection in your <VirtualHost *:80> containers is unnecessarily complex and the non-www to www redirect in .htaccess is incorrect (you are removing the URL-path).

For example:

RewriteEngine on
RewriteCond %{SERVER_NAME} =www.example.com [OR]
RewriteCond %{SERVER_NAME} =example.com
RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]

There is no need to check the SERVER_NAME in this <VirtualHost> container. The SERVER_NAME must already be one of the two values you are checking for otherwise it would never be at this point in the code in the first place.

And, unless you have plans to implement HSTS, then you might as well redirect to the canonical www subdomain (which you are doing later in .htaccess) in order to avoid a double redirect.

So, this could be simplified to a single mod_alias redirect:

Redirect 301 / https://www.example.com/

Repeat for your subdomains.

(Aside: Ideally, you would also have a separate <VirtualHost *:443> for the non-canonical non-www version of each domain that issues a simple redirect to the canonical www version. Although this does admittedly involve more code. Alternatively, you could use a mod_rewrite redirect in your existing <VirtualHost *:443> containers, similar to what you are doing in .htaccess.)

.htaccess

RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^(.*)$ https://www.%{HTTP_HOST} [R=301,L]

This removes the URL-path from the request and always redirects to the document root, which I'm sure is not the intention. (It would be bad for SEO and besides, why are you capturing the URL-path in the RewriteRule pattern and not doing anything with it?)

You need to include the $1 backreference in the RewriteRule substitution, for example:

RewriteRule (.*) https://www.%{HTTP_HOST}/$1 [R=301,L]

You will need to make sure you have cleared your browser cache.
