Connectivity issue: Authentication Failed IPTV66

[ALBERTUKU]

I Had kodi 17 with stalker plugin working fine, yesterday I noticed when I tried to login it reported "Authentication Failed". I read on this forum that URL has changed, so I pointed to the new URL, but the "authentication failed" error continued . I did everything like uninstall/install kodi, even trying v16 , reset, change mac, change clientid I run out of steam I'm frustrated trying to make it work again. Please I would need some help, what can I do? I have other iptv services working fine, so it seems to be something with IPTV66. Below you can see a portion of the log, I scrubbed details regarding to my subscription, but I can send you a full log in a private:

I couldn't get stalker to work either so I used this to install Xstream and it works fine: http://iptvtalk.net/showthread.php?26949-How-to-SETUP-Kodi-with-IPTV-Rocket-NFPS-66
