I can't connect to my server

In February the server was working fine. I started the server again in march so me and my friends could play on my server. The server started up and said Done! When Anyone tried connect it just said connection timed out.

The only way the server actually works is if I leave the server ip blank and connect trough localhost.

These are the server.properties
