After upgrading to Ignition-7.9.9-linux-x64 from 7.9.6 Ignition OPC UA went into a fault. Rediscovering OPC endpoint, restarting OPC module does not help. The gateway architecture and the environment show N/A.
When I change the Ignition server IP address to something outside the PLC address subnet, the Device becomes unreachable (understandably), but the OPC connection comes up as good!
Please give your ideas what this can be.
