**I play on multiplayer servers. My skin says its uploaded, but on other player screens it is Default skin.

My skin does not work. I succesfully uploaded onto mojang. It said i uploaded successfully. On some multiplayer servers (Mainly Creative) My skin does not work whatsoever. My screen shows i have the skin uploaded, but on Other players screens, it is showing the default skin. It shows my skin when i go on f5, or "e".
The skin i am using is Below.
