Cannot configure SDK to run with containerised app

I have .Net Core 6.0 web app hosted in the beanstalk env as a docker image. I don't see any batches submitted to the daemon, although everything is configured and started, according to the logs. I have the same issue when I run it locally with a local daemon. But if I'm running the app without the docker, as a usual process, the daemon starts to receive the samples. This gives me an understanding that the SDK configuration is correct. But why it can't reach the daemon from the container?

The app in containers on the local machine has this in the log
