Apache default page on installation

Installing the latest version ISPConfig-3-stable.tar.gz with php7.4 no issues occur during installation.
Accessing https and P:8080 only shows the apache default page same when acessing it with https and fqdn:8080

Installation output:
php -q install.php
>> Initial configuration

Operating System: Debian 10.0 (Buster) or compatible

Following will be a few questions for primary configuration so be careful.
Default values are in [brackets] and can be accepted with <ENTER>.
Tap in "quit" (without the quotes) to stop the installer.

The next two questions are about the internal ISPConfig database user and password.
It is recommended to accept the defaults which are 'ispconfig' as username and a random password.
If you use a different password, use only numbers and chars for the password.

Accessing via http results in Bad Request (Instead use HTTPS scheme to access this url, please.)
Have tried several guides, last one was: perfect-server-debian-10-buster-apache-bind-dovecot-ispconfig-3-1
OS is debian 10 with latest updates.

 

Does the "new" guide/installation method also support using a different SQL for the primary DB dbispconfig?

 

Goal is to do a setup like these: ispconfig-multiserver-setup-debian-ubuntu/
but using a different sql server for the dbispconfig and the customer DBs.

Like these in the "old" setup:

Code:

MySQL server hostname [localhost]: 192.168.1.xxx
MySQL server port [3306]:
MySQL root username [root]: ispconfig_root
MySQL root password []: PASSWORD
MySQL database to create [dbispconfig]:

 

Thanks for this hint.
We have a three node SQL cluster in place, is there any way to use this server for all nodes instead of a local DB on each Server?
