**UPDATE - Re-read your Post and missed that you are using versions 7.7 & 7.8. You need to update to latest version 16.5(See link in Post#1 of this Thread)
Yes, it changed months ago!
.tv changed to .ru
* I think they left both URL's valid, for users time to make changes. Maybe this period has ended.
I included both url's (.tv and .ru Server portals) in the IPTVXtra2 settings, almost a year ago, and posted a notification.
Change your Portal in the IPTVXtra2 settings and shutdown Kodi.
(Recommend you now do an IPTV Reset on your Account info page (may not be required, but just to be safe)).
Restart Kodi.
Launch IPTVXtra2 and upon startup, select update all, selecting all VOD categories you use and PPV.
Shutdown and restart Kodi and IPTVXtra2
