SERVER HELP!! (sloved)

I have had my server for quite a while and me and my friends could connect fine. I have port forwarded and EVERYTHING. Recently when i came home from Vaca, I tried to connect to my server using my IP address like i always do, but i recieved the message " Can't Reach Server". Here's the weird part...I can connect when switching the IP to 'localhost' or ':25565' . Someone help fast. I am hosting a Hunger Games lobby tomorrow and need to have my server working. Thanks.
