HalfdanOMG

I made my own resourcepack and i have tested it in singleplayer it works. But when i add it to the server everyone except me trying to join gets stuck on Mojang loading the resource pack. I then tried an other resource pack that is not mine and that works. So i dont understand whats wrong with mine. Link: https://www.dropbox.com/s/rrvqfefvvyxagmd/Installplz.zip?dl=1
