Unable to push to dockerhub. Constant timeouts

General
1

Using docker-machine on osx.

When I call docker push, it is very likely that the push will fail with an i/o timeout at a random step. e.g.

$ docker push synesso/apache-php-tippecanoe
The push refers to a repository [docker.io/synesso/apache-php-tippecanoe] (len: 1)

If I do this enough times, it will probably work. But it’s very frustrating. In fact, I’ve been running a while true loop waiting for it to succeed.

This happens not just with this image, but any image. It started occurring 1 to 2 months ago.

How can I improve this?
