I am using 8.0.11 Ignition platform and trying to connect OPC connection to local host. I am using opc.tcp://localhost:8088/discovery to connect to local server. But it is always displaying time out. What else can I do to resolve this. I am using Chrome browser for web gateway. I am new to ignition and have started working on it from past month. ---

The default port for the OPC UA server is 62541. Port 8088 is what the web server you’re accessing the Ignition gateway uses by default. You should already have a loopback OPC UA connection defined by default, are you trying to add a new one or connect from a 3rd party client? ---

Kevin, when i use 62541 port for OPC UA server there is a loop back connection but it’s OPC UA connection status says it is faulted. No, I am not trying to add any third party client.
