After automatic installation of ISPconfig 3 the server does not start?

Question

linux

I installed iSPconfig 3.1 on a clean Debian9 system via autoinstallation.
The script worked, it seems without errors, at the end it issued an invitation to the ip: 8080 panel.
An attempt to log in ended with the warning Possible attack detected right away. This action has been logged.
Did a reboot and that's it. The server is completely dead.
Ssh doesn't work, doesn't ping, doesn't boot at all.
Scanned by ip nmap no ports, no services.
Question: how famously did the autoinstaller kill a clean fresh system, and what should I do?
The system is on a flash drive, it is possible to pull out logs, or edit files. Where to dig comrades???
Ps I did the operation 3 times, I installed it on a clean system with an autoinstaller. There are no visible errors, but after reboot all 3 times the system is dead.
