Ctrl+dji is not connecting to my drone

Hi,
Recently I tried to connect my drone to ctrl+dji and use the pix4d capture software. But unfortunately no matter what I tried (reinstalling apps, downgrading apps, using another device (both android and ios) ) nothing seem to do the trick.
Can someone give me pointers on how this issue is raised and what solutions are out there to remedy this.
If downgrading have worked for someone else, what versions will do the trick.
Btw this was a different phantom 4, a week earlier I managed to connect some other phantom 4 drone.
Thank you
