Docker Insecure Registry Problem when `docker build' pulls base image - docker

Question

When using docker build, pulling the base image from a private registry fails with
http: server gave HTTP response to HTTPS client
It should not a problem of setting insecure-registries however, because
insecure-registries is set
docker pull and push are working without problems
I can workaround it by pulling the base image first and then calling docker build, but I would prefer to get to the root of the problem.
The problem occurred on Mac as well as Windows.
Any idea what might be the problem?
Edit: The solution of Dockerfile FROM Insecure Registry doesn't work for me.
For my insecure-registries entry I use ip:port. When I try to enter http://ip:port I get an error message:
Error invoking remote method 'desktop-backend': Error: "invalid daemon settings: \"insecure-registries\":\n Must be host[:port] or CIDR"
