WARP Won't connect on my Asus Zenfone Android 8.1 VPN enabled

I enabled the with WARP on the app to be used all the time on my mother’s phone. Enable it on the VPN option at the settings’ menu. Even disabling the Block non VPN connection, the app keep show that there is no connection despite my Wi-Fi working with non-warp mode and without the app enabled.
Also there are apps in this case YouTube and Google Photos, that are excluded and I can’t remove them from this list.
