It might be, because I created a newly staging version of my Dockerfile, since the MIX_ENV var does not seem to have never been properly passed to the Dockerfile through the toml file.

Is there something wrong with my builder instance? It is like this since two days.
I also have the feeling that the step with “sending the build info to docker” takes way more time then it used to.
If you need more info, I will happily provide it. I am a bit in a loss here.
