Apache2 - SSL não está funcionando

No momento, estou tentando instalar um certificado SSL emitido pela Namecheap pela Comodo. No entanto, estou tendo problemas atualmente. No log de erros, tenho este erro:

[Sun Apr 10 17:59:06.567045 2016] [mpm_prefork:notice] [pid 613] AH00169: caught SIGTERM, shutting down

AH00016: Configuration Failed

Os arquivos que recebi do Namecheap são os seguintes:

• meu-dominio_com.crt
• meu-dominio_com.p7k
• meu-domínio_com.ca-bundle

Eu gerei um arquivo server.key, bem como um arquivo server.csr.

Minha configuração do apache é a seguinte:

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

    ServerName my-domain.com

    DocumentRoot /var/www/html

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

    #   Server Certificate Chain:
    #   Point SSLCertificateChainFile at a file containing the
    #   concatenation of PEM encoded CA certificates which form the
    #   certificate chain for the server certificate. Alternatively
    #   the referenced file can be the same as SSLCertificateFile
    #   when the CA certificates are directly appended to the server
    #   certificate for convinience.
    SSLCertificateChainFile /etc/apache2/ssl.crt/minecraft-multiplayer_com.crt
    SSLCertificateKeyFile /etc/apache2/ssl.crt/server.key
    SSLCACertificateFile /etc/apache2/ssl.crt/minecraft-multiplayer_com.ca-bundle

Eu configurei o SSL no Apache com a2enmod ssl. Não estou muito familiarizado com a configuração de certificados com o apache, portanto, qualquer ajuda que você possa fornecer será apreciada.
