Well!!!!!!!!!!!!!! I just made a minecraft server. i have been working on it alone for quite a while now and now its time i get some staff.. I tried to get a few friends on. However, even though (I think) i portforwarded they cannot get on. It gives them this message

Failed to cnnect to server connection refused:connect

This is the message it gives my friends. I have the latest version of mac product(doesnt change much about the portforwarding) But if it does, can someone please help me out, i would really appreciate it, ive spent hours trying this
