HttpClient timeout in Docker container

asp.net

So, it's a weird thing. I have a docker network with two containers attached, one cli frontend one aspnetcore backend.

The problem: Running the CLI inside the container times out, both when using the raw container ip of the backend and the intended way using the container name (so

http://senf-app:5000

http://senf-app:5000

in my case)

What's even more weird is that this is a C#-only issue, because this works fine:

docker exec -it senf-cli curl http://172.18.0.3:5000/healthz => {"status":"healthy"}

docker exec -it senf-cli curl http://senf-app:5000/healthz => {"status":"healthy"}

docker exec -it senf-cli curl http://172.18.0.3:5000/healthz => {"status":"healthy"}

docker exec -it senf-cli curl http://senf-app:5000/healthz => {"status":"healthy"}

But I get this error:

'[command] --api-url http://senf-app:5000' timed out

'[command] --api-url http://senf-app:5000' timed out

when running inside the container.

I already tried forcing Ipv4 resolution in the http client of the cli, no results. I also tried configuring the network in different ways, with ipv6 enabled/disabled, ipv4 enabled/disabled. I just cannot get the CLI to work

What am I missing? What am I doing wrong?
