Cause

The error message occurs when NetPath has reached the endpoint server but the port was closed.

Resolution

The endpoint service must be running on tcp/161 not udp/161.
NetPath probes TCP ports.
If it is truly tcp/161, use PsPing (© 2019 Microsoft, available at https://docs.microsoft.com, obtained on March 15, 2019) to test the port availability from NetPath probe machine. The error message NetPath reported means NetPath reached the endpoint server but the port was closed.
