Hi,

I need your help because I have this error java.net.SocketException: Network is unreachable: connect. I think that due to this error I cannot browse in Ignition Designer the OPC-UA tags.  
Here are the details:

Under the Configure area of the gateway, on the left find OPC-UA \> Settings and check the “Endpoint Address” setting. Make sure it’s either localhost or preferably the actual IP address of the computer the gateway is on, then restart the UA module.
