Dahua integration not working with Dahua NVR304L-32-16P-EI

I have tried everything I can think of and can’t make this work. The card first displays a static image but then give this error “Failed to start WebRTC stream: webrtc: streams: exec/rtsp [rtsp @ 0x7fa22d8d0000] method DESCRIBE failed: 404 Not Found [in#0 @ 0x7fa22dc12c00] Error opening input: Server returned 404 Not Found Error opening input file rtsp://127.0.0.1:18554/camera.cr_1_cam_main?audio&source=ffmpeg:camera.cr_1_cam_main%23audio%3Dopus%23query%3Dlog_level%3Ddebug&log_level=debug. Error opening input files: Server returned 404 Not Found”
Running HA on HAOS on OracleVM running on Win11. Any suggestions would be appreciated.

Have you tried using the core ONVIF integration rather than that 3rd party one?

I used it for a while with my Dahua cameras, had no issues. I’ve since moved to Scrypted NVR though.
