It is up. Best places to check are in the announcements thread and in the IPTV Private Servers subforum. If there are issues, one or both of those places will reflect the situation.
Lino, have you been able to get it going again? Im having the same issue with NFPS. Not able to view actually streams. Started about 30 minutes ago. Seems to connect fine, until I actually click on a specific channel.
SAME HERE TOO i wonder if this new maintenance update mean slow internet persons are illiminated so to view from now on mean setting up a faster internet or hit the road jack
The OP is talking about not being able to access channels, not that the channels are having issues, as you are suggesting.
For the OP and others with a non-connection issue, I would reboot the modem, router and device. If that doesn't do it, close Kodi and do an IPTV Reset.
