I am also having the same issue. My Ignition OPC-UA Server is “faulted”. I can not connect any modbus device to my ignition gateway. How to allow permission to perform this operation?

Here is my log:

```auto
UaServiceFaultException: status=Bad_UserAccessDenied, message=User does not have permission to perform the requested operation.
