My Minecraft skin won't work?

So about a week ago i changed my minecraft skin. It will load if i go into singleplayer games and it will load in Lobbys. Like for example if i were to join the Hive server my skin would be there but when i join a game, hide and seek for example, it goes to the original Steve skin. I've tried to use at least 4 different skins and they are all doing the same thing. I've tried changing my version to 1.8, 1.7.10, and 1.7.9. They all do the same thing. Any way i can fix this?
