Connection timeout trying access an exposed port via host.containers.internal from the container itself

[simorex80]

Bug description

Creating a container that expose a port and trying to access the exposed port via host.containers.internal (from the container itself) generate a connection timeout. Accessing others ports exposes by others containers works.

Operating system

Windows 11

Installation Method

Installer from website/GitHub releases

Version

1.6.3

Steps to reproduce

• podman run --name web1 -d -p 8080:80 nginx
• podman run --name web2 -d -p 8081:80 nginx
• podman exec -it web1 bash
• curl http://host.containers.internal:8081 (Works) (Access to web2 via host.containers.internal)
• curl http://host.containers.internal:8080 (Don't works) (Connection timeout accessing itself)

No response

[jeffmaury]

Cannot reproduce. I followed the exact same commands as yours

[simorex80]

@jeffmaury Did you launched the curl command from inside the web1 container? podman exec -it web1 bash curl http://host.containers.internal:8080

[jeffmaury]

Yes I used the exact same commands

[slyfer]

Same happens to me, the request "freeze":

root@4d7b39548456:/# curl -v http://host.containers.internal:8080

• Trying 10.88.0.1:8080...

10.88.0.1 is the gateway
