Freepbx installation problem on Debian

Hi all,
I’m trying to install Freepbx on Debian 12 in a VPS Contabo following this guide.
Once the script has been performed, everything seems to go well, but at a certain point the SSH connection closes and I can no longer access, neither with SSH nor via the web.
I have no problems formatting and reinstalling, only I would like to understand how to do it to work.
Thank you.

Hi @bulldozer

Is there anyway for you to connect console like if its VM then connect VM console or if its appliance then console cable to see what does the system shows you ?

If you can ssh via console to the system by entering root password then you can check the sshd and apache2 process status or if the processes are running then its not ip blocking situation.
