Connections lost with Subscriptions - by: Wagner

Hi there,

we have got an issue regarding subscriptions.

We subscribe several things and get after some minutes the atattached messages.

The OPC UA server is a S7 OPC UA server.

If we test the same things against an free OPC UA server everything works ok.

My question is, why your OPC UA client cannot connect to the server or why the server rejects the connection after a while.

Where do the errors BadSecureChannelClosed and BadTcpInternalError originate from?

We tried to check the server logs. But the only thing listed was, that the client has canceled the connection.


Thanks for an advice.


Best Regards

Robert
