The server may have rejected the connection because it does not trust the client (e.g. certificate problem); check the diagnostics on the server side, if possible.
A possible cause of this error could also be that the OPC-UA server is not running, or that it has rejected the connection due to security reasons.

---- REMARKS ----
The server may have rejected the connection because it does not trust the client (e.g. certificate problem); check the diagnostics on the server side, if possible.
A possible cause of this error could also be that the OPC-UA server is not running, or that it has rejected the connection due to security reasons.
