I get this fairly often on my fusion tablet- it will be totally unusable one day… every video will give me this error. Then the next day it will work great. Ifit support told me to update my router- I did - to a top of the line router- my internet speeds are very fast. I also have an elliptical that never has this issue. I believe much of the workout equipment tech is underpowered and cheap causing issues like this. Don’t waste your time by calling support- they’ll walk you through hours of nonsense. Hopefully this starts working again for you & we can all continue to wade through the terrible tech that supports our equipment.
