Server will not start up

My FXServer seems to be running, but it will keep saying: [23:46:31][Monitor] (HB:–|HC:1) FXServer is not responding. (HB Failed) [23:46:31][Monitor] Still waiting for the first HeartBeat. Process started 60s ago". It will say that until the server restarts. The resources work as I have used them before. So does the VPS.
