"Connection refused" when using host network in Docker in GitHub Actions

I am starting a Docker container with Chrome inside, as follows:

docker run --rm --cap-add=SYS_ADMIN --network=host selenoid/vnc:chrome_117.0

In my local machine, this container listens to incoming requests in the following URL: http://localhost:4444/

Nevertheless, I have a "connection refused" error when trying to connect that URL (http://localhost:4444/) after starting that image (using the host network) in GitHub Actions. The error I get in Java is the following:

Caused by: java.net.ConnectException: Connection refused (Connection refused)

Can I use the host network in GitHub Actions?

    It is solved as follows:
