Hello XWikiers,
I have installed XWiki 13.8 on my Debian 11 based Server as docker container.
I was able to get through the initial setup after starting the containers. I was also able to install one extension Task Manager through my XWiki intial page (I have not copied the URL). When trying to install any other extensions I am getting the data.server not reachable error and the docker container for Xwiki-data stops. I can restart the container, it goes through the initial settings from 12% - 50% spinning for a while and loading the page, but the icons are not shown and when I click on something the docker container stops.
