A lot of the streams that KODI links to don't work all the time. Doesn't mean that your internet connection is bad. Try a different KODI add on and see what happens. Exodus is very popular.

I have a similar problem where none of the apps in kodi find streams (including exodus). If i try google play it says no servers available same for uTube. However, if i go to the browser i can surf the internet. Is it possible that my ISP (same as my Cable TV provider) is blocking me as everything worked fine the first day I installed it.
