Fail2ban Missing in v4.0

Hello,

After successful installation of v4.0, I noticed the fail2ban is missing in /etc directory even though the package is installed.

I went through the install script and I noticed the following;
`wget --no-check-certificate https://latest.astppbilling.org/fail2ban_Cent.tar.gz
tar xzvf fail2ban_Cent7.tar.gz
rm -rf /etc/fail2ban
cp -rf /usr/src/fail2ban /etc/fail2ban`

The problem here is that wget --no-check-certificate https://latest.astppbilling.org/fail2ban_Cent.tar.gz return connection refused while installing (and still does if you go to the URL), hence, no fail2ban_Cent7.tar.gz was downloaded and files in /etc/fail2ban were deleted.
