Connectivity error to SIMIT

I need to connect the VisualComponents with SIMIT.
When I tried to test the connection I got these error message:

*Connectivity error: SIMIT - Server - Client application cancelled the request.*
*GrpcStatusCode: Cancelled*

I used VisualComponents 4.7, SIMIT V11.1 and the actual coupling software. Both are running on the same PC.

Does anyone have an idea how to solve this?

I suspect it could be a firewall issue. Make sure that the firewall is not blocking the port.
You can check this link on how to open ports in the firewall:

Thanks for your answer.
I tried this before and when I checked it in the resource monitor it shows me that the ports are permitted and not restricted.
I know in general how to set up a rule for the firewall. And I think I did it right. But if someone can told me how exact the rule should be set up. I would like to try it. :slight_smile:
