Remote OPC issue

[ADrugay]

Hello to everyone.

I have an issue with starting of my remote OPC manager.
We have several PCs with this project.
In some machines it works fine.
But in one its not starting.
Everywhere im using different -num id
But in logs when starting is writing an error:

What can i do wrong?
Steps were too easy
Copy project. Regsitration. Change num Id. Starting. And its work fine in most cases....

It looks like there is already a manager of type "device" connect to the Data Manager at server 2.
With the debug flag "-report dispatch" you can check the current manager connections for the Data Manager at server 2. Maybe in this debug output you can see why the manager cannot connect.
