can't play songs on tablet

[Jusavallintaus]

I have installed tablet on my car but i can't stream any songs from spotify. when i select song it shows it is starting, but then the song just disappears. i can't even download songs. when i factory reset the tablet it will let me use spotify for maybe 20mins and then it won't work anymore. i have tried clean reinstall, but won't work longer than 20mins.

i share wifi from my phone to tablet.

youtube and other apps works just fine, so it should not be about internet connection.
