Hi,
well I am totally fresh around IPTV as till yesterday I haven't even heard about that... So I noticed some cheap subscriptions on Aliexpress, asked for trials and received few m3u links for testing.
Well, as they work great on my Win10 VLC , I totally can't get it working on my Kodi 17.6 (latest Libreelec).
I've installed IPTV Simple Client exactly like here: http://xtremestreams.com/wp-content/uploads/2017/12/EPICSTREAM-Install-Guide-with-Kodi-using-PVR-Client.pdf
I've also installed few more addons like here: https://www.youtube.com/watch?v=OYiOjsc33io
At the end I get around 3000 channels listed in the client, but I can't start single one.
I click on it, blue circle/arrow flashes for a few milliseconds (like it does when I start a video file) and... that's it, nothing else happens.
Any ideas what can it be? I've read about spoofing user-agent, but it seems it was a problem few years back not today.
Post your Kodi log and I'll take a look. Turn debugging on first.
