Hello,I have a server running NetXMS and NextXMS Agent (v 3.5.90) on CentOS 8, and I cannot get DCI data from the NetXMS agent running on the server itself, that is, all Internal DCI work perfectly, but, for example, the default "NetXMS server: physical memory used by process" DCI always returns "<<ERROR>>" (see first image)

I tried getting the DCI value by nxget and it works only if I use 127.0.0.1 as host address, while it gives "500: Internal error" if I use any of the two "real" IP addresses of the server (see second image).

It seemed like the agent was only listening on the loopback address, so I tried to add the two IP addresses to the MasterServers parameters, in the Agent's configuration file:

MasterServers = 127.0.0.1, 192.168.200.103, 192.168.24.249

and now nxget works with both IP addresses (see third image), but I'm still getting "<<ERROR>>" in the UI.
Am I doing something wrong?

Thanks,
Alessandro
