RTP not working

I am currently starting with the Hello AI World course, but i cant seem to get rtp to work. I have tried following the steps in the video (s3e1) as well as playing around with hostnames and ip addresses, but no success. The port is 1234 as shown in the course.
Whenever i try to open the stream in VLC Player, either via a sdp file or manually, it either gives me an error or stays black. (the camera is working though).
The Jetson Nano is connected via Ethernet, the Laptop via Wifi. I attempted to ssh over both wifi aswell as usb but it made no difference.

Please refer to the steps in
Jetson Nano FAQ
Q: Is there any example of running RTSP streaming?

Check if you can run RTSP successfully.
