in Loginserver.ini
change loginserver=127.0.0.1
to loginserver=99.99.99.99 (your server ip)
in eqemu_config.xml
change <address>Serving Machines IP</address>
to <address>99.99.99.99</address>
if you still have issues, make sure your database is up to date with format changes.
Edit: Another thing to check is that you have the correct IP address in the account file under minilogin_ip. If there is no matching entry it will go back to login screen. ( I had that problem with typo in account table ).
