I have some remote IoT devices that I routinely remote into via Tailscale and view the camera feeds. However, this suddenly stopped working and I cannot seem to figure out what is going on.
IoT device: Ubuntu 18.04 Jetson nano with GStreamer 1.14.5
Client: Windows 11 with GStreamer 1.24.10
IoT Pipeline: gst-launch-1.0 -v audiotestsrc ! udpsink host=100.72.23.20 port=5055

Client Pipeline #2: gst-launch-1.0.exe udpsrc address="100.72.23.20" port=5055 ! fakesink dump=TRUE

I know the data is being received by my computer (otherwise I would’ve leaned toward this being a Tailscale issue) because packet data shows up in wireshark and Windows 11 task manager.
