Just installed VitalPBX 4.2.0-1 as a proxmox vm - no webinterface?

Hi All

Brand new to VitalPBX, and just wanted to take it for a testdrive.
I downloaded the ISO, and created a VM as per the instructions, followed them all the way through.
It shows the green VitalPBX logo now, and gives me an IP, and I can ping that IP.
But if I enter the IP into the browser, it redirects me from http to https and fails to show the webinterface.
I don’t have any certs on it yet.
If I do a status on Apache, it says the vitalpbx.conf is invalid!?

Nov 25 14:01:55 vitalpbx apachectl[1542]: AH00526: Syntax error on line 2 of /etc/apache2/sites-enabled/vitalpbx.conf:
Nov 25 14:01:55 vitalpbx apachectl[1542]: Invalid command 'Header', perhaps misspelled or defined by a module not included in the server configuration
Nov 25 14:01:55 vitalpbx apachectl[1539]: Action 'start' failed.

Now what?

Strange, can you try with Debian 12?
Then it will be Vitalpbx 4.5

Or try with a clean Debian 11 if you want v4.2
