Question

I have a live domain which is working perfectly without SSL but on SSL it will showing me following page Error Image: https://i.stack.imgur.com/9GXjO.png

For this made changes in following files:
000-default:

<VirtualHost *:80>
    ServerAdmin mymail@gmail.com
    #DocumentRoot /var/www/
    DocumentRoot /opt/tomcat/webapps/ROOT/WEB-INF/
    Redirect  "/" "https://www.mydomain.in/"
</VirtualHost>

default-ssl:

<IfModule mod_ssl.c>
    <VirtualHost _default_:443>
        ServerAdmin webmaster@localhost

        #DocumentRoot /var/www/html
        DocumentRoot /opt/tomcat/webapps/ROOT/WEB-INF/
        SSLCertificateFile  /etc/ssl/certs/mydomain.in_ssl_certificate.cer
        SSLCertificateKeyFile /etc/ssl/private/_.mydomain.in_private_key.key
        SSLCertificateChainFile /etc/ssl/certs/DigiCertCA.cer

    </VirtualHost>
</IfModule>

apache2.conf:

<Directory />
    Options FollowSymLinks
    AllowOverride None
    Require all denied
</Directory>

<Directory /usr/share>
    AllowOverride None
    Require all granted
</Directory>

<Directory /var/www/>
    Options Indexes FollowSymLinks
    AllowOverride None
    Require all granted
</Directory>


<Directory /opt/tomcat/webapps/>
    Options Indexes FollowSymLinks
    AllowOverride None
    Require all granted
</Directory>

I that my project is located inside /opt/tomcat/ and not inside /var/www/

Please help me to solve this. I cant understand exact issue related with it
