Typo3 11 on virtual server, error logging in from host machine

Hello everyone,

I have installed typo3 11.3.3 on a virtual machine running in Oracle VirtualBox. I managed to set it up so I can access the server from the host machine. However, when I try to log into the backend of typo3 from the host machine, I get the following error:
“POST http://localhost:8000/typo3/login?loginProvider=1433416747 404 (Not Found)”
I have tried Firefox and Chrome and get the same result in both browsers.

Logging into the backend from the guest machine is working fine though. Can anyone give me a hint to what the problem might be?

Host machine
OS: Windows 10

Guest machine
LAMP stack with

  • Debian 11
  • Apache 2.4.48
  • MariaDB 10.5.11
  • PHP 7.4

Virtual Network Setup: NAT with port forwarding from :8000 (host) → :80 (guest)

This is the first time I’ve used VirtualBox, set up a server and used typo3, so please don’t assume any expertise :wink:

Best, Pascal
