[Can't connect to my own server?]

Hey guys, please help. My friends are getting really frustrated and they really want to play :(

[Can't connect to my own server?]

Hey guys! I was hoping you could help me out here today, I recently had made a Tekkit server using hamachi and everything <was> going fine. I then opened my server today and I get the following error "Can't reach server" and obviously my friends got this error aswell. Could you guys help?
