HI Support,
I have already successfully set up connections to the OPC DA from VTscadaLight. Unfortunately, I have not yet been able to configure a successful connection via OPC UA.
My attempts with a PLC have failed in the same way as with Kepware.
Below I have given my configuration with screenshots.
I need urgent support for one of my students for a project. With other software products, the connection with OPC UA has been problem-free so far.
I would be pleased to receive a quick reply.
Best regards, Jan

From the endpoint data the server is configured to use a secured connection, so the certificate offered by the service must have the correct info, e.g. the server FQDN used in the OPC UA Client Driver Connection tab must match that the server certificate.

For a test environment it would easiest to configure the server to only support an unsecured connection, i.e. remove all certificates from the server and only configure unsecured endpoints.
