IPTV66 Stalker Client Authentication Failed. Retrying

IPTV66 Help here!
I've changed the URL, performed an IPTV reset and changed the MAC and still getting authentication failed. Anything else I should try?

first make sure you are connected to the internet the same message comes up if your connection is down, next double check all you data for simple errors like a comma instead of a period it all has to be exactly correct. learning to use copy paste (cntl c and cntl v) this can help eliminate typos.

Internet is fine as I'm posting here and all other network activity is fine. As for the entered data I've tripled and quadrupled checked the settings with no luck, I've also disabled my VPN. I've now reached my maximum searches for the day.

I couldn't get stalker to work no matter what I tried but I was able to get Xtream working, though the guide it has seems to be wrong.
