Minecraft launcher not connected to internet

I am unable to log in. I've recently purchased a new Minecraft account and re-downloaded the launcher, but every time I input the correct Email and password it says on the top right corner "Sorry! Make sure you are online and try again" even though I am connected to my internet. I've read other issues about this, and I've heard that it might be a "launcher_log.txt" or "nativeUpdaterLog.txt" problem, so I've uploaded both of mine. Please, help me.
