Additional environment details

Windows 11 Enterprise, 22H2, 22621.4460

On Windows Server 2022, error messages are slightly different.
Error: initializing source docker://registry.access.redhat.com/ubi8-micro:latest: pinging container registry registry.access.redhat.com: Get "https://registry.access.redhat.com/v2/\": dial tcp 23.51.14.174:443: i/o timeout"

Additional information

On podman-machine-default /etc/environment.d/default-env.conf contains proxy environment variables.
But systemctl --user show-environment does not print proxy environment variables.

'>podman machine ssh
$ systemctl --user show-environment
.... (no proxy variables)

systemd appears to be starting up before the file /etc/environment.d/default-env.conf is created.
systemctl --user daemon-reload command updates systemd and podman pull works right.

$ systemctl --user daemon-reload
$ systemctl --user show-environment
http_proxy=proxy.company.com:8080
https_proxy=proxy.company.com:8080
...
$ exit
