Sorry this screenshot doesn’t help.

Can you get a Wireshark recording of Ignition connecting to this server?

edit: and actually, can you get the rest of the logs? And navigate to the Status section of the gateway and find this OPC connection and check the fault reason and stack trace? In 7.9 this application URI message should only be a warning and not what is preventing you from connecting.
