[QUESTION] Encountered zmq::error_t when executing roslaunch.

[Speike-SHL]

Hello, I've successfully completed the build using catkin build. However, when I attempted to start the system with the command roslaunch hydra_ros uhumans2.launch, I encountered the following error. I'm hoping you can provide a solution.
