This error message appears when Minecraft cannot connect to the internet. Check your network connection and your firewall/antivirus settings.

It can also sometimes happen when the Mojang servers are offline. In that case you just have to wait a few minutes and then try again.

  • It works on my mac, but not on my laptop.

  • Then look at the differences between the two. Like network connection, firewall, etc. Commented Oct 11, 2017 at 23:19
