i keep getting this error "Authentication server are down. please try again later, sorry!"
i have a ubuntu 16.04 server running minecraft 1.10.2
Are you using a proxy? I don't know about auth servers but I have almost same error when using proxy on Windows 10.
Player p = Bukkit.getServer().getPlayerExact("Mr_Matwin3");
Bukkit.BroadcastMessage(ChatColor.RED + "" + ChatColor.BOLD + "Mr_Matwin3 is awesome!");
Bukkit.BroadcastMessage(ChatColor.RED + "" + ChatColor.BOLD + "I am still awesome! :P!");
i fixed it
turns out that my server provider blocked the authentication server
i told them to unblock they change the ip and boom i can connect to my server again =D
