What endpoint URL are you using? Can you provide a screenshot of where it gets stuck and upload your log files? ---

Ignition's OPC UA server listens on 62541 by default, so I'm not sure there's really an issue. ---

Troubleshoot the tag using Tag Browser, not the Window Designer. But first get your OPC connections working. You need to explain your setup. - Is the Siemens device a simulator or a real PLC? - What is its IP address? - How have you configured the device in Ignition? - What is the connection status?
