Answer
version.dat file was missing from the UCMDB Server's root folder.
This caused the server to think its version is 0.0, and try to "downgrade" the Class Model when asked to download it by the probe.
Eventually this caused an exception when trying to download the __Ver8CmdbClassModel.bin when in-fact the file that should have been downloaded is the regular class model __CmdbClassModel.bin.
We have copied the version.dat from the probe's folder to the server's folder.
After that the probe was downloading resources successfuly.
