I run the deepstream5.0 app example on JetsonNX. When you reinsert the network cable, the following error occurs, causing the program to exit. This error seems to be caused by the failure to obtain the RTSP stream, and the probability of this error is high.

Also, if there are multiple cameras in the App Source configuration, but one of them is disconnected from the network. Running the deepstream-app program in this state causes the following error:
