Error starting the initial installation in the PROXMOX container

Hello everyone!

Today I made two attempts to install the software on my server and produced the same error twice, each time on fresh containers.

Installation on a PROXMOX container with Ubuntu 22.04 and minimal equipment according to system requirements. System is currently installing Docker and Docker-Compose as per the description. Installation routine without incident. And when starting then the error as illustrated:

What am I doing wrong or what am I missing?

Thank you for your time
