Build was canceled without errors

Hi
for some reason the build of our game gets canceled but no error or warning is provided.
Is there a way to get a more detailed log than the "Full Log" in Cloud Build?
Thx in advance!

1: Running Prebuild steps
2: done.
3: bvr 1.0.1
4: bvr-api 0.1.3
5: Using strategy: Default

Same thing here. It's the first time we are trying Unity Cloud Build... at first we had some errors, so we fixed them, and now the build gets canceled at the end and starts a new one, without throwing an error nor a warning.

1: No Library cache found - ALL assets will be re-imported.
2: [Unity] Initialize engine version: 5.1.2f1 (afd2369b692a)
3: Build was canceled
4: Unity Cloud Build restarted this build process, look for the next one.

Any ideas?
Thanks
