Launcher stuck on downloading external libraries

Whenever I try to load Minecraft, my launcher gets stuck on this:

It will be random, occasionally Guava and all the other libraries.
To fix the issue, I have to restart the launcher 10+ times and it's a huge pain. It can't be a connection issue, because when it's loading I can browse the web just fine.
