We have not found a solution yet. However working with Software AG support they have told us this:
Development is going to make a change that should resolve this.
They are going to now use the localhost IP as the Natural ONE address if we know that the application server is running locally ’ . We used to obtain the address via “InetAddress.getLocalHost().getHostAddress()” but depending on the environment the returned ip-adddress was not the one of the local machine but from a different.
Via using localhost IP when we know that NaturalONE and the application server run locally the problem is fixed .
Dont have an ETA on the patch yet.
