Force Wifi Connection

I’m have a Pixel XL with project fi as my provider. I’m connecting to a raspberry pi that is running kodi and acting as an access point. I’m able to use Yatse to connect but in order to control kodi but I have to turn my mobile data off on the phone. I believe the phone is trying to send the commands out the mobile data because it detected the wifi connection does not have internet access. In my yatse host settings I have only connect on wifi checked. I’m not sure if this issue can be resolved with yatse or if it needs to be fixed at the phone settings. Please let me know if you have any advice on how to resolve this issue.

Well without logs it’s hard to says anything

But from the description it sounds like something that needs to be fixed on the phone, Yatse have no control over the route taken by the network packets.
