Minecraft launcher could not connect to server?

What do I do? I looked at a similar question to mine and there was an answer saying to make sure Java is allowed past the firewall. So I checked and it already is. I've tried uninstalling and installing both Minecraft and Java but nothing has changed. This link says that all services are fine, so what's going on? I bought a 2nd account to use as an alternative in-game account and now I can't log in.

(I cleared the email and password boxes for obvious reasons in this screenshot: security purposes)

Solution 1:

I've had the same thing happen to me on my laptop. Try rebooting the game and then your router.
