In the awx_web logs shows an error 400 code:

I am also seeing this behavior on a fresh install of AWX 1.0.7.2 on CentOS 7

The 400 response should give details of what happened, but it could be that https://github.com/ansible/awx/issues/2446 is blocking the proper reporting of those errors.

@rgruyters we think we may have resolved this in a newer version of awx. Could you try the latest (3.0.0) and reopen if you're still seeing problems?

[rgruyters]

@ryanpetrello unfortunately my project has finished at the company where I have implement this. Also in the end we moved to the enterprise version, Tower.
