APM webtop + portal access DNS error
we use v14 with partitioned environment, each partition has own route domain with strict isolation enabled. We have APM with webtop and few links in it. One of them is a portal access which points to server IP address. We cannot use FQDN as APM uses system DNS and we cannot use system DNS for customer environment.
Anyway, since we use IP address as a resource item it should be OK, but is not, user access to portal access fails at "DNS lookup error. The requested server does not exist.". Using hostfile does not help, it is ignored by APM. What are the options to fix it?
