Can't connect to my own Minecraft server? - 1

Ok so me and my friends played on my server two weeks ago and it was working perfectly fine. Up until now, the server's been untouched for a while and we can't connect to my server (I'm the host). I don't know what's happening. The error message I get is

java.net.connectexception: connection refused

My ip address is the same and of course I port forwarded it a long time ago. It's just unusual how it's happening now. Can anyone help?

Try to disable antivirus or windows firewall because it could block the connection. And try to port-forward again, because your computer ip is still the same but your internal ip (in the modem) could change. Eg: it could change from 192.168.1.2 to 192.168.1.3 or 192.168.1.4.
