I have the same issue while watching suddenly says Authentication problem and kicks off then i have to log in to the account and reset iptv restart profile and re enter password and user name
this is started to happen too often two or three times a day
i was trying to set up iptv stalker and getting no luck.. everytime i click on NFPS i get error 111 connection refused.. not that good with these kind of things so hard to figure out to me
