Hi,
I am using MATLAB/Simulink R2022b and want to connect to a ROS2 Humble network on a Ubuntu 22.04 machine, with an arrangement as per screenshots extract, listening to a topic.

Every time I run, the error message in the last screenshot shows up. I cant quite understand what i have to do. Sure this topic is published on the network. Therefore I got the subscription...
Thank you for your help.

I can see an overlapped subscriber block just back on the forefront subscriber. Can you try to remove the subscriber back?
