Hello @nicola.esposito,

The message `BAD_NETWORK_VERSION` can indicate that the server and the viewer are from _different_ versions/releases. For example, the server is from a later release and the viewer is from an earlier release (and vice-versa).

Also, I just noticed a [similar post](https://forum.techsoft3d.com/t/issue-with-model-rendering-in-hoops-communicator-2024-6-0/4100/1) in the forum and was wondering if they are regarding the same issue.

Thanks,  
Tino
