AdventurousButterfly15 The fact that it tries to ping localhost means you are running the ClearML server locally right? In that case, it is a docker thing: it cannot access localhost because localhost inside a docker image is not the same one as your machine itself. They're isolated.

That said, adding --network=host to the docker command usually fixes this by connecting the container to the local network instead of the internal docker one.

You can add a custom argument either in the webui after you clone (see screenshot) or by using set_base_docker https://clear.ml/docs/latest/docs/references/sdk/task#set_base_docker

So normally task.set_base_docker(docker_arguments='--network=host') should work. Fingers crossed 🤞

(I don't have a local server available now, but if you want I can try to recreate later)
