I get "Server (URL) connection timeout", "Check playlist URL" or "No playlist uploaded" messages, when starting the app, while my playlist URL that works on my computer, other devices and apps.
Try example test list http://siptv.app/lists/example.m3u (external URL) first, then then check your playlist
for errors. Make sure your URL is a direct link, not a redirect and that it is currently online. You can also try
downloading your playlist file by putting the playlist URL in the internet browser address field and use it as
a static playlist at My list page.
In case of Check playlist URL you can try turning off your TV/device from power cord for ~1 minute to
clear device cache. Also try long pressing "0" or "CH", or long mouse click "Reload" button to force
reload of playlist URL (disable app cache).
Additionally, try reducing your playlist size by removing channels/movies (especially if you have LM series
LG TV with limited memory). If your playlist doesn't appear on TV or disappears after restart, try
checking Save online box, when uploading the playlist. You can also try resetting Smart HUB or turn your
TV off and on to clear the TV cache if you have Samsung TV.
TVs have limited memory available for app storage, so if your playlist is too big (~5 Mb), it will fail to save
in TV's memory.
