A little while ago I started experiencing a problem with my Minecraft launcher. I could only 'Play Offline', and when I tried to connect to a server I got an invalid session. Somewhere (I forgot where, sorry) some guy said to logout and log back in. I did this, and now I can't log back in. I get this message:
Sorry, but we couldn't connect to our servers.
Please make sure that you are online and that Minecraft is not blocked.
*(EOF Exception: SSL Peer shut down incorrectly)*
The launcher log from before I logged out is at http://paste.ubuntu.com/16580291/.
