What version of Ignition are you using? There should be an error message with a fault reason on the status page, what’s it say? ---

This is just a standard network-level error. Ignition is trying to open a TCP connection and getting no response. Make sure the server is running, you’ve got the right IP address, and there’s no firewall blocking any outbound connections. There’s nothing wrong with your configuration in Ignition right now. ---

How I am sure the OPC UA server is running properly or not? ---

Which OPC UA server? You should probably start a new topic with a more detailed question.
