Hi, I was connecting to OPC UA but it says it was faulted as show in the photo below.

Upon checking the fault:  
no matching endpoints found

UaException: status=Bad\_ConfigurationError, message=no matching endpoints found

You’ve changed the connection configuration in some way that doesn’t match the server configuration.

Running through the endpoint discovery wizard again by following the “endpoints” link on the OPC UA connections config page may get you going again.
