Can't pull anything behind corporate proxy

[KiwiKinon]

Hi,
I want to use Podman behind a corporate proxy on Windows 10. Everything works fine with Docker but nothing passes with Podman.
The installation is good, the machine init is done, the machine is started.
When I try to pull this is the message I get :
Trying to pull docker.io/redhat/ubi8-micro:latest... Error: initializing source docker://redhat/ubi8-micro:latest: pinging container registry registry-1.docker.io: Get "https://registry-1.docker.io/v2/": dial tcp: lookup registry-1.docker.io: Temporary failure in name resolution

I tried to modify the containers.conf (C:\Users<myProfile>\AppData\Roaming\containers\containers.conf) like this :

That doesn't change anything, I still get the exact same error.

I'm up for any beginning of solution !
