Does it work when you try to connect to 127.0.0.1?
Nope. It tells me "Connection Refused: Connect," like it did all the other times, which I probably should've said.
I also tried localhost.

Sounds like a software firewall might be stopping the minecraft server from actually making any sort of connection.
In your firewall's settings, add an exception for the minecraft server (or java itself, whichever works).
If you have a router, ditch the software firewall.
This guide I wrote is about terraria, but it's the same situation for minecraft, check it out.

If you're using a router, then by default incoming connections fail before they even reach your computer (so your software firewall is protecting against things that never even reach it). In addition when you do need to host (and thus port-forward to allow a connection to your computer), then you need to add an exception into your firewall anyways to allow the program to communicate, so in that situation as well the software firewall isn't doing anything (since it's set to not block that connection).
With the rise of routers (and gateways), software firewalls have become almost obsolete for home users since the main purpose (blocking incoming connections) is naturally accomplished with routers.
I can't connect to my own LAN server. It's hosted on my own computer. I made my IP static, and took the IPv4 address from the ipconfig command in the Command Prompt and put it in Server.properties. When I try to connect, it says can't reach server. All my search results are for public servers, not LAN ones.
What on earth is wrong, and why is nothing I try working, even though it apparently works for everyone else?
