Redirect HTTPS and HTTP Requests to Web App in Tomcat from Apache

I have a spring web application running in tomcat which I can access using https://example:8080/myApp. I have installed Apache2 to redirect port 443 requests to tomcat. now I can Access my application without the port number. I have installed SSL certificate using LetsEncrypt and all HTTP requests are forwarded to https. when I enter my domain in the browser, it is taking me to tomcat home, not to my web app. This is my virtual host config for 443

<IfModule mod_ssl.c>
    <VirtualHost *:443>
        JKMount /* ajp13_worker
        ProxyPreserveHost On
        ProxyRequests Off
        ServerAdamin webmaster@myDomain
        ServerName example.com
        ServerAlias www.example.com
        ProxyPass https://example.com http://localhost:8080/myApp
        ProxyPassReverse https://example.com http://localhost:8080/myApp
        <!--ssl details-->
    </VirtualHost>
</IfModule>

Why it is not redirecting to myApp. Any help will be appreciated. Please ask if you need more details.
