Minimserver 2 doesn't start when Fedora 35 starts

[Le Dom]

Hi,
Ive installed Minimserver 2.1 without problem on Fedora Server 35 headless.
I have enabled autostart but Minimserver doesn't start when Fedora starts.

So I have create a service file minimserver.service in etc/systemd/system but Minimserver doesn' start.
Here is the result of ^C
[root@00-A0-C9-01-03-35 ~]# systemctl status minimserver.service:

× minimserver.service - minimserver 2

I have tried to use rc.local but I get the same error.
Do you have an idea or a solution?
Many thanks in advance.
