Hello Hui, I'm not sure if this is really a certificate issue. Because as i saw in your slides you are already connected. The address space of the server is shown (slide 7). To have a more detailed diagnostic it would be helpful to see a log/ trace of the Siemens client. Is this possible? Also there are may some Rexroth server logs inside the Diagnostic Logbook. Have you checked this? Regards Matthias
