We have an IBHLinkUA OPC Server setup at our Site. I was trying to use a Kepware's KEPserverEx UA Client Driver to communicate with the system and read the OPC tags setup on the UA OPC Server. We exchanged the Server and Client Driver certificate to communicate between the systems. When I try to connect to the UA OPC Server, I'm getting the following Error :


24.08.2017 15:15:05 Error OPC UA Client Channel 'IBHLinkUAPC03' failed to connect. (error: 0x80AF0000, BadInvalidState).

I have been trying to find more information on this error. Does anyone know what causes this error and how to resolve it ?

Thanks.
