Nuendo 11.0.10- Nuage FADER-MASTER don't start NUAGE IO A16 out of workgroup

Hello
I installed Nuendo 11.0.10.321 and Nuage Fader and master do not start,
and in addition the Nuage io A16 interface exit the Nuage Workgroup Manager.
All work great in Nuendo 10.3.0.184
Please

Maybe check out the Firewall Settings for N11.

Yessss Hendrix97, this is the solution.
thanks, many thanks
