Can't access my container though Github Actions

I’m using this Go package to run a container during the tests. Locally everything works really fine, but at the Github Actions, I simply can’t connect to the container.
There is anything that I’m missing? Like, do I need to join some specific Docker network to be able to connect to the container?
For sure the container is running because I created a goroutine to print the containers from time to time and the container is there and the port mappings are correct as well.

@diegobernardes,

From the repository you shared, I did not find any workflow files.
If possible, please share the repository where you run the workflow, so that we can check the detailed configurations in the workflow to analyze the root cause.
