Did u got Rejected from server or Fail to connect.. that mean u put the wrong ip in ur clientinfo.. if u got rejected from server.. either u mess up ur Packet version.. or ur ip banned.. make sure to check ur subnet_athena.conf.. I got same problem before.. because
; Only set true if your server is set to use MD5 password
MD5 = false<---- i put this on "true" in the loki.ini
try double check everything.. related to client version, packet version and ip setting
