NFPS / Private cannot get MAG254 to autheticate

IPTV Private Server (NFPS)
That happened to me a couple of times. In my case, the url assigned by papiao changed when I switch to Donation. So now I open papiao and look directly under Donation. The url there is the correct one. Every time I get error in authentication I go to Donation under Papiao and look up the correct url. NFPS checker has the correct url also.
