Just attached a log file, hope it helps

Got the same problem:
-relogged in launcher
-restarted launcher
-reinstalled both minecraft and the launcher
-changed password (i've read on reddit that could be a hacking problem)
-rebooted windows
-tried on third part launchers (techniclauncher, curse (now twitch) launcher)
everything is vanilla: no mod, no launcher, no cracked client, no resource pack and so on

The issue persists.
