Describe the issue

i am unable to publish stream i tried anything publishing webcam stream or even mp4 file

echo testing | nc localhost 8554
localhost [127.0.0.1] 8554 (?) : Connection refused

i even have this error

Describe how to replicate the issue

1. start the server
2. i published it with
   ffmpeg -f v4l2 -input_format yuyv422 -i /dev/video0 -f alsa -i plughw:CARD=HD,DEV=0 -c:v libx264 -preset fast -tune zerolatency -c:a aac -b:a 128k -strict experimental -vf "format=yuv420p" -f rtsp rtsp://localhost:8554/room
   even tried
   ffmpeg -re -stream_loop -1 -i landyard.mp4 -f rtsp -rtsp_transport tcp rtsp://localhost:8554/live
   both have same error

Did you attach the server logs?
