First I've seen with that error. You should open a support ticket. ---

What actions led up to this error? Did you restore the gateway from a back up or reconfigure anything? You could try to regenerate the certificates and then disable/enable the OPC connection. **Gateway Web UI → Connections → OPC → Security Settings → Certificates** Regenerate the client certificate first it looks like you have an error with it.
