Resourcepack not loading

Resourcepack not loading, I get an error in chat

• Minecraft limits servers resourcepacks size to 50MB, be sure to compress your textures and your music files before creating the zip file.

• Be sure that yourcustom_urlis a direct download link to the zip file. If you paste the link on your browser (Firefox/Chrome) you must instantly see the download start, if you see a download page with buttons it's wrong. Please upload it on Dropbox, generate the download/share link and change dl=0 to dl=1 at the end of link.

• Be sure to follow all tutorial steps
