Motioneye with webcam ip

[UsefulVid]

I like to use my old pixel 4a as a security cam.
I installed the pro version of webcam ip and started the rtsp stream.
The internal url is:
rtsp://192.168.0.115:8080/h264.sdp
I also used user and password authentication.
I can add the camera but the picture of the camera is only grey and I am unable to get it working.
It shows no obvious error and the android app shows no active connections.
What am I doing wrong?
