Opentrack no video problem

I’m trying to setup DroidCam + AiTrack + OpenTrack, but I can’t get Opentrack to find the video feed from the phone. Droidcam & Aitrack are both working fine. I have used same port numbers in all apps, and set AiTrack ip 127.0.0.1. but still the opentrack says “No Video” when I press start. Others with same issue found a fix?
