Sling TV not working lately...loads but won't play any channels

[GodsPeace]

It worked when I tried it a couple times but then a week later it was telling me poor internet connection then stopped doing that but would load up to the point I can press play but it just blinks for a split second and doesn't play. Is Tesla screening out Sling? I should try YouTube and see. Sling plays fine on 4g on my phone.
