SS IPTV

I am getting "Failed to load external TV Guide" error when opening my channel list

I tried the following headers with x-tvg-url in my m3u file:

#EXTM3U x-tvg-url="http://m3u4u.com/xml/x79znke4qgbgmmzngk24"
#EXTM3U x-tvg-url="http://m3u4u.com/xml/x79znke4qgbgmmzngk24#format=xmltv"
#EXTM3U x-tvg-url="http://m3u4u.com/xml/x79znke4qgbgmmzngk24.xml"

Please help! I am using the LG App.
