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.

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

is there any solution?
