I know this topic seems to get raised every couple of months but as far as I can tell I've followed the steps discussed in other posts to no avail. I've got a gateway running the opc ua server running on a remote machine (ip: 192.168.95.42) and I'm trying to connect to it currently using UaExpert (with the eventual intention of connecting using some C# I've written) and the /discovery endpoint. My server settings currently look like this:
In UaExpert I'm attempting discovery at opc.tcp://192.168.95.42:62541/discovery and it is just failing. Interestingly trying to use that address for the gateway's own OPC connection also fails but works fine at opc.tcp://localhost:62541/discovery. I've turned off the firewalls on both ends for the time being also.
Is there anything else I'm just completely missing to make this work correctly?
Yes I think so? I'm not so great with network related questions if I'm honest but that's the only IP address that's listed when I run ipconfig in a command prompt window. Here's my zipped wrapper.log file: wrapper.zip (106.0 KB)
Also make sure there's no 3rd party firewalls enabled. Another way to check what IPs are available to Ignition is to look at the Status->Overview page under the Environment section. There should be an entry named "Detected NICs" with a list of all your IP addresses that Ignition sees.
From the machine where UaExpert is installed, can you open the gateway web page at 192.168.95.42 ? If not, a network path between the machines may not exist.
