Uploading DICOM-RT files through the REST API works fine. Two reasons can explain your issue:

1. Your Orthanc instance is protected by HTTP authentication, in which case you have to add the username and password at the last command-line arguments to "ImportDicomFiles.py".
2. The content of your local storage is compressed (check the "StorageCompression" in the configuration file of Orthanc), which prevents "ImportDicomFiles.py" to properly read the DICOM files. In this case, you will have to use generic replication: https://orthanc.chu.ulg.ac.be/book/users/replication.html#generic-replication
