Slave DNS Manager: Connection refused

Hi!

I just installed the Slave DNS Manager to use a vServer as a slave NS. But the status in the extensions settings is red and commented with the following error:

Error Code 1: rndc: connect failed: 88.***.***.****#953: connection refused

Named.conf.local and named.conf.options are correct corresponding to the output in the extension settings.

Port 953 is also opened:

iptables -L
ACCEPT tcp -- anywhere anywhere tcp dpt:953
ACCEPT tcp -- anywhere anywhere tcp dpt:953

Maybe the NAT is...
