how to run caddy with selinux of fedora (lemm.ee)

how can you run caddy with a Caddyfile with systemd with enabled selinux on fedora?

I can manually start caddy with caddy start or /usr/bin/caddy run --environ --config /etc/caddy/Caddyfile which is also in /usr/lib/systemd/system/caddy.service.

Caddy works just fine but I can't start it with systemd without disabling selinux with sudo setenforce 0.

edit:

I found a tutorial on how to start caddy on centos that disables selinux, starts caddy with systemctl and then enabales selinux again. That does not sound right to me.

I agree! Thx for asking. I don't get a proper one.

$ sudo systemctl start caddy 
Job for caddy.service failed because the control process exited with error code.
See "systemctl status caddy.service" and "journalctl -xeu caddy.service" for details.

$ journalctl -xeu caddy.service
