When a device I’m reading tags from gets turned off, the OPC-UA Server shows a “java.net.ConnectException: Connection refused” error. Is this normal? I would have expected that the error would indicate a time-out.

The entire error details is:

Whether the ConnectException’s message says timed out or connection refused is likely an implementation detail (in the JDK) that we don’t have any control over. I wouldn’t worry about it.
