I have been getting "Error 900.primetime.102100.5" on ESPN and ESPN2 HD channels the past couple of days using the Contour app on PC or tablet. Regular standard ESPN and ESPN 2 channel works. Other HD channels also stream fine via the Contour app. Any idea why ESPN HD channels are having this error? Thanks.
I think it's a DNS error. Try flushing your DNS cache? Or if easier, try setting your DNS static to 8.8.8.8 and 8.8.4.4?
