RTSP streaming out error after restarting Xavier NX

I have been running many different Deepstream programs streaming out RTSP with out any hitch.
I powered down Xavier NX last night and when I restart this morning I cant get any program to stream out
RTSP streams.
This is the error im getting

Error:gst-resource-error-quark: Could not get/set settings from/on resource.
(13):gstmultiudsink.c(1278): gst_multiudsink_configure_client ( ): /GSTPipline:pipeline0/GstUDPSink:udpsink:
Could not join multicast group: Error joining multicast group:No such device

Any ideas

I was checking out my Xavie rNX and noticed one of my antennas had popped off at the board. Popped it back on and now everything works. . ???
