Minecraft help, can't login, or play online multiplayer servers?

I can't play online on servers so i logged out and i can't log back in, it says that i can't connect to minecraft and that i should check if minecraft is blocked. It isn't, i checked every firewall at least 10 times… Nothin is wrong… Internet works great and java is updated to the latest and i still get this message when starting the mc launcher…

Looking for update
