From Syracuse Server 12.6.XX and 11.19.XX

A bug has caused the parameter System.BindIP in the nodelocal.js file to be referenced by the system as System.BinIPnull.

This parameter allows you to restrict the listening on a specific IP

If you use this parameter, please duplicate it as below:

system: {

    bindIP: "172.1.1.1",

    bindIPnull: "172.1.1.1"Syracuse Server 

},

Note: Do not remove the initial key (System.BindIP). A hotfix will be provided as soon as possible for this and it will be usable again.
