Inner Exception 1:
UAEngineException: UA SDK error (Opc.UA.ServiceResult=0x808A0000) in 'DiscoveryClient.GetEndpoints'. OPC UA service result - Error establishing a connection: BadNotConnected.
+ The error occurred when preselecting an endpoint for discovery URL "opc.tcp://192.168.1.100:40853/Pilz/PSS4000OPCServerUA".
+ Connection attempt #1; last connected at 0001-01-01 12:00:00 AM (local); unconnected for 00:00:00.0470000.
+ Some possible causes of this error are that the OPC-UA server is not running, or is not configured to listen on the specified port. Also, the network connection may be broken (cable unplugged?).
+ The client method called (or event/callback invoked) was 'DataChangeNotification'.
Inner Exception 2:
