Access to YouTube app being blocked at specific times over LTE

[Ryanstech]

I've been unable to access my youtube app over the mobile network every day at very specific times. During my commute home in the evening access to my youtube app is completely blocked ("no network connection"). However I have a strong signal and all other network activity works fine, even access to youtube's website. This is a recent problem and is very suspicious to me. Is this a sly way of trying to control network congestion? I hope not..
