Community server container keep restarting

We noticed that you are using Debian 11. I checked the information about Debian and unfortunately Debian 11 is not supported at the moment (internal bug number - 53124). The issue is mostly related to systemd which is not supported by the OS. So try to use Debian 10 which has been tested and works. We will add support for this operating system, but I cannot provide you with timeframes at the moment.
