Minecraft server connection issue?

I just tried setting up a Minecraft server today and it's currently working fine for me, but my friend can't connect to it for some reason.

She keeps getting this error message:

io.netty.channel.AbstractChannelAnnotatedConnectException: Connection timed out, no further information:

What does this even mean?

I've set up a port/NAT thing with the correct IP and everything, I have no mods/resource packs enabled on the server itself, I added Minecraft and Java SE all as exceptions to my firewall, and I've even allocated more ram to the one server for just two people.

What else is there?
