IPTV Stalker Not Working

IPTV Stalker addon is no longer working for me.

When I go to click a category it tells me "stalker is offline".

I am using the portal.iptvprivateserver.tv url,I have right click the NFPS and cleared cache.
The custom MAC address is the same as my donation.

Any suggestions ?
thanks
 
Where was clear cache

go under video addons and click on iptv stalker, you will then see nfps or in my case it was "iptv usa & latin america" which ever one you see, you need to highlight it and right click (if on a PC) or pull up the context menu (if on an android) by hitting c on keyboard or clicking the menu button on the remote. you should then see the clear cache option. clear the cache, restart kodi and hopefully it will load up.
 
IPTV Stalker working fine for me, on the PC Kodi 15.0. You could try clearing the cache files manually, by going to your userdata\addon_data\plugin.video.stalker folder.
