Connects to live TV the first one I do but then won't connect again

I have a cottage with 2.5 mb download speed in the winter and the first time I connect to live TV it works. It won’t work again after this? I can watch recordings ok. Im thinking it’s because my tablo isn’t connected to any channels the first time any thoughts?

What end device? I know the last Android Tablo app update fixed this particular issue on my phone.

Fire tv
