Getting Started with Docker

Hi all,
I am new to all things Synology and Docker.
I have been trying to get the linuxserver/qbittorrent container up and running.
I have installed the image and started the container via the Webui form within the Synology NAS.
All the how-tos I have seen are installing the image and running the container from an ssh terminal which I have tried but can’t get to work either. Maybe it’s me but I don’t know what I am doing wrong.
Is there a difference between installing and running the container from the webui compared to a ssh terminal?
When I have the container up and running I am trying to log into the Webui via its IP and port number but can’t get it to work.
I know there is a lot going wrong with my setup but please point me in the right direction.
What am I doing wrong guys?
