Mapping subdomain to tomcat web application

I have a subdomain test.example.com. I have a java web application running in tomcat 8.5 on port 8086.

In /opt/tomcat/conf/server.xml I have a virtual host defined like below.

<Host name="test.example.com" appBase="webapps/myapp-0.2" unpackWARs="true" autoDeploy="true">
        <Alias>www.test.example.com</Alias>
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               prefix="test_access_log" suffix=".txt"
               pattern="%h %l %u %t &quot;%r&quot; %s %b" />
      </Host>

I have an apache2 conf defines like below. /etc/apache2/sites-available/test.example.com.conf

<VirtualHost *:80>
        # The ServerName directive sets the request scheme, hostname and port that
        # the server uses to identify itself. This is used when creating
        # redirection URLs. In the context of virtual hosts, the ServerName
        # specifies what hostname must appear in the request's Host: header to
        # match this virtual host. For the default virtual host (this file) this
        # value is not decisive as it is used as a last resort host regardless.
        # However, you must set it for any further virtual host explicitly.
        #ServerName www.example.com

        ServerAdmin webmaster@localhost
        ServerName test.example.com
        ServerAlias www.test.example.com.com
        DocumentRoot /var/www/test.example.com/public_html

        <Directory /var/www/test.example.com/public_html>
                Options Indexes FollowSymLinks MultiViews
                AllowOverride All
                Order allow,deny
                allow from all
        </Directory>

        # Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
        # error, crit, alert, emerg.
        # It is also possible to configure the loglevel for particular
        # modules, e.g.
        #LogLevel info ssl:warn

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

        # For most configuration files from conf-available/, which are
        # enabled or disabled at a global level, it is possible to
        # include a line for only one particular virtual host. For example the
        # following line enables the CGI configuration for this host only
        # after it has been globally disabled with "a2disconf".
        #Include conf-available/serve-cgi-bin.conf
</VirtualHost>

In public_html I have .htaccess defined like below.

RedirectPermanent / http://test.example.com:8086

My goal is to be able to hit the myapp-02 tomcat web app on port 8086 like so http://canicarry.thehatapps.com:8086

I’m not sure what’s wrong but I get 404. I can’t seem to resolve http://canicarry.thehatapps.com:8086 to my web app running in tomcat.

Any help would be appreciated.
