Issues adding nodes for Juniper Firewalls

Hello,

I am trying to some Juniper SSG Firewalls nodes so we can monitor their syslog messages.

I have configured each FW for syslog messages and pointed them to the LEM server;

Although, when I go to add any of the 20 plus FW's I need to monitor I get the following and the node never appears;

Any ideas as to where i'm going wrong? Thanks!
