Now when i changed quotation marks, and wanted to rebuild app, it told me to update the Docker. Now Im unable to rebuild an app cause of that:

`fatal: unable to access 'https://github.com/SamSaffron/pups.git/': Could not resolve host: github.com`

Changing DNS and restarting docker like described [here](https://meta.discourse.org/t/could-not-resolve-host-github-com-for-samsaffron-pups-git/32050) didnt solve it.

Getting more and more frustrated…
