Server problems

hey guys im having a connection error from metrics, it started yesterday after some trouble with a hacker, probably using nodus or something, i looked online and found some one had the same problem n his advice was to reset my router and re port forward and reopen the server, and that's when the connection problem started it looks like this in my console
07:01 PM [INFO] [Metrics] Connection reset
07:11 PM [INFO] [Metrics] Connection reset
07:21 PM [INFO] [Metrics] Connection reset

08:11 PM [INFO] [Metrics] Connection reset
08:21 PM [INFO] [Metrics] Connection reset
