ERROR STREAMING RTP Session

Hello, I am working on streaming with a zed2 connected to a jetson Nano, today I got this error, I looked in the forums and I did not find what it was due to.

Hi,
Can you specify the JetPack used on the Nano? + the ZED SDK version.

This error code means that the RTP backend used for streaming could not be created because it cannot bind the RTP/UDPv4 socket on the desired port. Do you specify a port in the streaming configuration?

Hi the image shows the Jetpack version and the zed SDK version is ZED Tegra JP43_v3.5.0

and if I specify the port and it is 30000

Socket cannot be bound on this port. Most probably, the port is already used by something else.
Try to change the port number to something else to see if it change
