I am trying to connect and consume data from the Ignition OPC UA server. I have following settings: Bind Port: 62541 Bind Address: localhost End Point Address: 192.168.68.67 (This is the machine with Ignition) Security: None,Basic128Rsa15,Basic256Sha256 User source: opcua-module (default) Now on the UaExpert (latest version) machine (192.168.68.69) In the custom discovery I have following: opc.tcp://192.168.68.67:62541/discovery After select discover nothing is happening. Not sure what is wrong! Any help will be appreciated. Thanks ---

If UaExpert is on another machine you need to set the bind address to something like `0.0.0.0` and restart the server for it to take effect. ---

I changed the bind address to 0.0.0.0 and restart OPC UA module and as well the ignition server. But still no luck with connection. ---

You might also need to open firewall ports on your server. ---

Thanks @pturmel and @Kevin.Herron. So applying inbound firewall rule and bind address did the trick. ---
