Cannot reach immich web-interface on proxmox

Hi everyone, My question my seem silly, but as I am installing immich for the first time. The docker compose works fine, but I can not reach the web interface on either ports: 2283 or 3001. It runs on an Ubuntu Server host VM in proxmox. I did the changes recommended by Alex regarding the proxy and web containers, was it to soon? Thank you in advance for your help.
