Shared project: "Project Download failed" error

Hello folks,

Shared project. Computer A was the owner and the project was stored locally in it. Computer A was supposed to add dialogue markers for ADR, while Computer B was dedicated to foley sync.

Computer A could make changes and commit them. However, when we made changes and pressed the commit button on computer B, we got the following errors:

“Copy Error” and then “Project Download failed”.

From this point on, it was not possible to update either the project on either side. The network sharing was corrupted.

¿How do we go around this error? ¿What did we do wrong?

We tried restarting nuendo, re-sharing the project and creating a new project from scract. No cigar.
