xymonproxy strange behavior

hello

I got a server A my central hobbit 4.2.0 server.
I got a server B my local xymon 4.3.0 RC1 server running a xymon proxy on vip:1984 and running the real xymond on 127.0.0.1:1984.

the xymonproxy config is :
[xymonproxy]
        ENVFILE /opt/xymon/server/etc/xymonserver-proxy.cfg
        CMD $XYMONHOME/bin/xymonproxy --server=10.64.3.6,10.64.3.9,127.0.0.1 --report=$MACHINE.xymonproxy --no-daemon --pidfile=$XYMONSERVERLOGS/xymonproxy.pid --listen=$XYMONSERVERIP --log-details --debug
        LOGFILE $XYMONSERVERLOGS/xymonproxy.log


from the central I'm querying the local with :

/opt/hobbit/server/bin/bb local "query local.dm"


The strange behavior is :

 if I got the server var in xymonproxy config with 127.0.0.1 in last param it's working. If not It's not working. 

Strange isn't it ?
