Ecostruxture OPC UA Server Expert

[Han_Stra]

Our plant in India is provided with a Modicon580 PLC. An automatisation consultant has succesfully configured two connected PC's with SCADA (Citect). On a 3rd PC (MS-Windows 11 Home), we want to have access to an OPC UA-server to do additional process analysis. For this purpose we have downloaded and installed EcoStruxture OPC UA Server Expert (vs. 2.0) on that PC connected to the PLC. With the OPC configuration tool (3rd PC) and the EcoStruxture Control Expert (vs 15.1) on one of the SCADA PC's we have configured the settings as shown in the Youtube-video (How to Enable OPC UA Communication with Modicon PLCs).
If we start the OPC-UA server we get the message:
"The application EcoStruxture OPC UA Server Expert will be stopped now. The server is configured to use domain 192.168.0.117 which does not appear in the certificate. Update the server certificate by performing 'Repair' using setup of EcoStruxture OPC UA Server Expert".
where 192.168.0.117 is the IP-address of the 3rd PC.
We have searched but we cannot find how to perform the 'Repair'.
Can someone give us some help?

We did not find a solution for the problem. Finally we have installed the OPC UA-Server on one of the SCADA  PC's. On this PC the OPC-UA server starts successfully without error message. On the 3rd PC we can access the OPC-UA-server with our OPC-UA-client without any problems.
