I have been trying to get the new web interface (war) working in our system. Our webserver is on a different server from the netxms server itself. With the old webserver we had the nxmc.properties file to set the server= parameter but with the new interface when I try to log in I get a "Connection Refused" response instead of logging in. I can log in if I change back to the legacy war file.
I will check with developers, but most probably reading of this property is not yet implemented in the new UI, as it's still under development.
I can confirm that changing server is not implemented yet in new web UI.
Best regards,
Victor
