How to configure two applications on apache2

What I would like to achieve is to get two separate links linking to two different applications.

http://hostname.com <--- wordpress

http://hostname.com/openproject/ <--- openproject or eventually http://openproject.hostname.com/ but this I guess would require actions on my VPS provider.

First application would be wordpress blog with configuration such as:

/etc/apache2/sites-enabled/wordpress.conf

<VirtualHost *:80>
        ServerAdmin admin@HOSTNAME_HERE.com
        DocumentRoot /var/www/HOSTNAME_HERE/wordpress/
        Redirect / https://HOSTNAME_HERE.com/
        <Directory /var/www/HOSTNAME_HERE/wordpress/>
                Options +FollowSymLinks
                AllowOverride All
                Order allow,deny
                allow from all
        </Directory>
        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

/etc/apache2/conf-enabled/wordpress.conf

Alias /wordpress /var/www/HOSTNAME_HERE/wordpress
<Directory /var/www/HOSTNAME_HERE/wordpress>
    Options FollowSymLinks
    DirectoryIndex index.php
    <IfModule mod_php.c>
        <IfModule mod_mime.c>
            AddType application/x-httpd-php .php
        </IfModule>
        <FilesMatch ".+\.php$">
            SetHandler application/x-httpd-php
        </FilesMatch>
    </IfModule>
</Directory>
<Directory /usr/share/phpmyadmin/setup>
    <IfModule mod_authz_core.c>
        <IfModule mod_authn_file.c>
            AuthType Basic
        </IfModule>
        Require valid-user
    </IfModule>
</Directory>
<Directory /usr/share/phpmyadmin/libraries>
    Require all denied
</Directory>
<Directory /usr/share/phpmyadmin/setup/lib>
    Require all denied
</Directory>

available with SSL through

/etc/apache2/sites-enabled/default-ssl.conf

<IfModule mod_ssl.c>
        <VirtualHost *:443>
                ServerAdmin admin@HOSTNAME_HERE.com
                ServerName ip.address.of.hostname
                DocumentRoot /var/www/HOSTNAME_HERE/wordpress/
                <Directory /var/www/HOSTNAME_HERE/wordpress/>
                     Options +FollowSymLinks
                     AllowOverride All
                     Order allow,deny
                     allow from all
                </Directory>
                ErrorLog ${APACHE_LOG_DIR}/error.log
                CustomLog ${APACHE_LOG_DIR}/access.log combined
                SSLEngine on
                SSLProtocol         all -SSLv2 -SSLv3 -TLSv1 -TLSv1.1
                SSLCipherSuite      ECDHE-ECDSA-AES256-GCM-SHA384...
                SSLHonorCipherOrder on
                SSLCompression      off
                SSLSessionTickets   off
                SSLCertificateFile      /etc/apache2/ssl/certificate.crt
                SSLCertificateKeyFile /etc/apache2/ssl/pkey.key
                SSLCertificateChainFile /etc/apache2/ssl/chain-ca.crt
                <FilesMatch "\.(cgi|shtml|phtml|php)$">
                                SSLOptions +StdEnvVars
                </FilesMatch>
                <Directory /usr/lib/cgi-bin>
                                SSLOptions +StdEnvVars
                </Directory>
        </VirtualHost>
</IfModule>

Second application would be openproject configured via:

etc/apache2/mods-enabled/passenger.load

LoadModule passenger_module /home/openproject/.rbenv/versions/2.7.3/lib/ruby/gems/2.7.0/gems/passenger-6.0.10/buildout/apache2/mod_passenger.so
<IfModule mod_passenger.c>
  PassengerRoot /home/openproject/.rbenv/versions/2.7.3/lib/ruby/gems/2.7.0/gems/passenger-6.0.10
  PassengerDefaultRuby /home/openproject/.rbenv/versions/2.7.3/bin/ruby
</IfModule>

/etc/apache2/sites-enabled/openproject.conf

SetEnv EXECJS_RUNTIME Disabled
<VirtualHost *:8080>
   ServerName IP_ADDR_HERE
   DocumentRoot /home/openproject/openproject/public
   <Directory /home/openproject/openproject/public>
      AllowOverride all
      Options -MultiViews
      Require all granted
   </Directory>
   <Location /assets/>
     ExpiresActive On ExpiresDefault "access plus 1 year"
   </Location>
</VirtualHost>

Application is available without SSL on http://HOSTNAME_HERE.com:8080 and any configuration which I have tried would work to host this application on http://HOSTNAME_HERE.com/openproject/

configuration which I have tried on /etc/apache2/sites-enabled/openproject.conf

SetEnv EXECJS_RUNTIME Disabled
<VirtualHost *:80>
    ServerName IP_ADDR_HERE
    DocumentRoot /home/openproject/openproject/public
    ProxyPass /openproject/ http://127.0.0.1:6002/openproject/ retry=0
    ProxyPassReverse /openproject/ http://127.0.0.1:6002/openproject/
   <Directory /home/openproject/openproject/public>
      AllowOverride all
      Options -MultiViews
      Require all granted
   </Directory>
   <Location /assets/>
     ExpiresActive On ExpiresDefault "access plus 1 year"
   </Location>
</VirtualHost>

Another try:

SetEnv EXECJS_RUNTIME Disabled
<VirtualHost *:80>
   ServerName IP_ADDR_HERE
   DocumentRoot /home/openproject/openproject/public
   Alias /openproject/ /home/openproject/openproject/public
   <Directory /home/openproject/openproject/public>
      AllowOverride all
      Options -MultiViews
      Require all granted
   </Directory>
   <Location /assets/>
     ExpiresActive On ExpiresDefault "access plus 1 year"
   </Location>
</VirtualHost>

Another try:

SetEnv EXECJS_RUNTIME Disabled
<VirtualHost *:80>
   ServerName IP_ADDR_HERE/openproject/
   DocumentRoot /home/openproject/openproject/public

   <Directory /home/openproject/openproject/public>
      AllowOverride all
      Options -MultiViews
      Require all granted
   </Directory>
   <Location /assets/>
     ExpiresActive On ExpiresDefault "access plus 1 year"
   </Location>
</VirtualHost>

and nothing was working. I have received either 301 or 403 or 404 errors. Please help me with my setup.

PS application internally is running on 6002 port
