I have an issue with about 20 Windows servers (different versions ranging from 2003-2016) that are not showing up in the Devices section of the Snow Inventory. Snow agent is deployed and running. I am able to telnet from the troublesome server to Snow Inventory server over port 443 we are using and also able to access the web page (https://snowinventory.int.sonofon.dk) for snow agent from the browser. Certificates for access to https are installed and present. Regardless of that I get the following errors in the log file:
2018-02-07T13:08:47+01:00; WARNING; snowagent; client\configmessagehandler.cpp; Client::ConfigMessageHandler::SendToEndpoint; A http send error occured with endpoint https://snowinventory.int.sonofon.dk:443. HTTP send error.: A security error occurred
2018-02-07T13:08:47+01:00; ERROR; snowagent; client\messageloop.cpp; Client::MessageLoop::Handshake; Handshake failed. Cannot connect to server. No endpoint can establish a connection to the server.
About 450 servers are running Snow agent in the same environment without any issues.
