- DOCKER_HOST env var was set to the builder hostname, which Docker treats as tcp://host:2375 and which overrides the active docker context, so the SSH remote-builder context was ignored (Cannot connect to tcp://docker-build.haven:2375) - context endpoint used a literal ssh://***@ instead of the docker_user input - create an actual buildx builder instance named remote-builder (build-push-action needs a builder instance, not just a context)
