Error: Host not found (11001)

Hello!

I'm using pmon_query command to collect information about managers in my net.
I resolved all addresses on all machines (added in .config localAddress = "").
I'm use .ctl script for collection data on redundancy active machine.

Where it working, in console has errors, like:

WCCOActrl (3), 2018.09.27 02:44:03.891, CTRL, WARNING, 54, Unexpected state, diagnostics\\managersInfo.ctl Library: C:\\Siemens\\Automation\\WinCC_OA\\3.15\\scripts\\libs\\pmon.ctl
Line: 261, tcpOpen, connect(s2012a:4999): Host not found (11001)

Line: 261, tcpOpen, connect(s2012b:4999): Host not found (11001)

I dont understand what is wrong.. ping command to all servers is good, net configuration has static addresses ipv4 and dns on ipv6.

So the commands 'ping s2012a' & 'ping s2012b' do get a response?
Can you also connect to the pmon with telnet/webbrowser?

1. yes
2. yes. I connect to the pmon with webbrowser and got page with pmons remote management

Note sure if this is related but we're facing similar problems.
Using pmon querys as well to monitor / start / stop managers.

The project used the pmon port 15001 befor migrating it to v3.16.
Afterwards we changed the port to 14001 but the functions paGetProjHostPort(...)/paGetProjAttr(...) are still delivering 15001 instead of 14001 which is listed in the config and used by the system.

Could you check this as well?

Best regards,
