V4 Cant get RTSP to work with Synology or VLC

I have been trying to setup My V4 RTSP on Synology Surveillance Station which cant detect it so I tried VLC with the provided link in the app for the camera. That also fails with

VLC could not connect to xxx

Your input can’t be opened:

VLC is unable to open the MRL xxx

Any Suggestions?

Since both Synology and VLC fail, I’d narrow this down by testing the exact RTSP URL in VLC from a device on the same LAN as the camera, using the camera’s current local IP. If it still fails there, the issue is between the camera and local network rather than Surveillance Station. Once VLC opens it locally, use that same URL in Synology.
