Upgrade to 8.0.9, delete the connection, then add the connection again and go through the discovery wizard. If there's any problems after that post the new error and a screenshot of each step of the discovery process.

Hi Kevin,
I did the Upgrade but the Connection still “FAULT”, but with other reason, see the log below:

This means you didn't configure a username and password but the server is expecting one.

I delete the OPC Connection many times, and did the upgrade, but still have this problemm??

I have the same error on the default Ignition OPC Server with endpoint opc.tcp://localhost:4096/discovery

I do not know what username and password it is asking for. (And I assume that this is OP’s problem as well)

I have found the answer to my own question in the User Manual.
