Build state pending


I imported successfully a project on github into docker cloud.
My first build worked as expected but the second one is going weird since I added another branch as source.

When triggering the build it is building for a couple seconds and then the state changes on the build page fo failure. But the build itself is still pending now for more then 30minutes.
Is this a problem on my side or a problem on docker cloud? Can I do something to fix it?

The docker status page is not indicating any errors on their infrastructure.
