GRC AC Integration with CUA create user

Hello experts

I am facing a problem with the integration of GRC -AC 10.1 SP8 with the CUA
Landscape requested by client needs that the GRC AC - create the user in the CUA and the CUA replicate this user to the satellite systems by assigning profiles requested by ARM

Account modification works 100% But I try to create a user displays the following error:

Central System not reached(RFC destination "my host" does not exist) Status = Failure

The steps reproduced are:

2 I created a connector group for SOLMAN:

3 In scenario settings integration , tied the SOLMAN connector for 4 types:

4 The last step , CUA Update settings , I activated CUA connector as GLOBAL:

(Maintain CUA Settings)

Thanks
