Hi there,

We have duty / standby servers running GeoSCADA with healthy OPC UA communications to the Turbines server. Everything is running smoothly with the communications until we reach the Duty / Standby checks.

If we shutdown Server A, Server B loses its connection to the Turbine server via the OPC UA. We believe that the Server B certificate and private key are still pointing to the Server A hence when the Server A is down Server B fails.

Is it possible to assign separate client certificates to A and B while they are accessing the same GeoSCADA database? If one fails, the other one picks its certificate and communicates with the Turbine Server.

If anyone happen to come across this situation, could someone kindly provide help?

Kind regards,

Sampath Bogavilli
