Offline mode stops working after 2 hours

[gameman338]

After I connect to Spotify online and go into offline mode it tells me i have 29 days before I need to reconnect to verify that I'm still a premium user. However, after 2 hours or less of using offline mode, the music stops and says i must connect to verify I'm still a premium user. This has happened every single time I've tried to use offline mode. How can i make it so that I only have to connect once a month rather than every 2 hours?
