Hello everyone here is the answer from microsoft support:
Hello,
We have worked on this problem and we have succeeded in reproducing the behavior you are experiencing. We are still working to find out why this is happening, but it will probably take time.
For the moment, as a workaround and not to prevent the deployment of Windows 10, I propose to use the local upload for the .wim image. Do not check the "Upload image to Windows Deployment Services server (optional)" option and save the .wim file to the machine. Then copy the .wim to the WDS server and continue with the deployment.
