How do you `docker push` from your laptop to the server with consumer broadband? I've heard docker times out after about 50-75%. Great fun.

This might be a "person in a country with pretty fast internet connection" opinion but I don't think I ever had that issue. Might also depend on the container size, pushing > 1GB containers might be more error prone than pushing small(ish) containers.

Sounds like you need a better internet connection.
