So today my Minecraft was working perfectly, then at around 7:30 P.M. MST I went into the multiplayer screen and on all of my servers it said "Can't connect to server". I tried restarting everything, I uninstalled and installed Minecraft again I rebooted my router many times I have 4 bars and it says that my signal strength to my Wi-Fi is Excellent yet I can't access any online Multiplayer servers! Every time I do try to join them it says 'java.lang.NullPointerexceptions: group. I do believe I have the latest version of Java installed as well. Also each time I try to go into one of my Survival Worlds my game crashes! Please Help Me!
