American channels not working on FireStick

I bought my FireStick about a week ago and cancelled my Sky TV subscription because KODI was far cheaper and also had way more channels. I also bought a month subscription to RUYA seeing it most of the free addons don’t work all the time. For the first 4 days everything worked fine, streams ran smoothly and had no issues but for the last few days I can’t seem to get the American channels to work, they either don’t go on or the just go in slow motion and buffer a lot. The audio is fine and I’ve tried turning the deinterlacing video off but nothing, any help?

Also forgot to note, all channels work fine on my laptop so doesn’t seem to be anything wrong with the provider.
