UM Connection not possible via Java Client "Realm not reachable"

Hello,

we’re having a problem with connecting a Java client to UM via nsps. It’s getting the error message realm not reachable. Although firewall rules between the consumer and um are prepared so that the access to the port is open. Does a client need to have more access to a UM server besided the port where nsp or nsps is available?

Hi, did you manage to resolve this at all? We’re having the same issue. Thanks.
