Hello. I am trying to start a 1.11.2 multiplayer map for my Youtuber friend. The server is running properly but once I and my friend enter the server, the minecraft client will tell us that it"Cannot find Minecraft Authenicated Server" while my server will tell me that it "cannot find the validate account".
I works when I set the online-mode to false. But, this will not show the youtuber's skin, which is bad to us.
I am asking that if there is a way to connect the server properly while online-mode is set to true.
(P.S.: We only have premium account and premium alt [alt that can run on premium servers] , none of us have any cracked account or alt)
(Another P.S.: The map we were trying to play and the server properties of my server can be find below)
