Podman "no route to host" when pushing to container registry with sudo, but works without sudo

I am encountering a problem with Podman on my system when I try to push images to a local registry. First, I start the registry container with sudo.

$ sudo podman container run -dt -p 5000:5000 --name registry docker.io/library/registry:2 

I can check the logs :

$ sudo podman ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES <id> docker.io/library/registry:2 /etc/docker/regis... 26 minutes ago Up 26 minutes ago 0.0.0.0:5000->5000/tcp registry $ sudo podman logs registry WARN[0000] No HTTP secret provided - generated random secret. This may cause problems with uploads if multiple registries are behind a load-balancer. To provide a shared secret, fill in http.secret in the configuration file or set the REGISTRY_HTTP_SECRET environment variable. go.version=go1.20.8 instance.id=id service=registry version=2.8.3 INFO[0000] redis not configured go.version=go1.20.8 instance.id=<id>service=registry version=2.8.3 INFO[0000] using inmemory blob descriptor cache go.version=go1.20.8 instance.id=<id> service=registry version=2.8.3 INFO[0000] Starting upload purge in 31m0s go.version=go1.20.8 instance.id=<id> service=registry version=2.8.3 INFO[0000] listening on [::]:5000 go.version=go1.20.8 instance.id=<id> service=registry version=2.8.3 

Then, I get this error when I try to push my image :

$ sudo podman push localhost:5000/my-image --tls-verify=false Getting image source signatures WARN[0012] failed, retrying in 1s ... (1/3). Error: trying to reuse blob sha256:<sha256>at destination: pinging container registry localhost:5000: Get "http://localhost:5000/v2/": dial tcp 127.0.0.1:5000: connect: no route to host Getting image source signatures WARN[0026] failed, retrying in 1s ...

However, if I do the same without sudo, it is working correctly.

I also tried to do it with sudo -E but I got the same error.

Any ideas ?
