Error in loading OData in Power BI

Hi everyone,

I am having a problem with OData connecting on PowerBi. I have tried several ways but could not connect to the Odata to Power bi. Can anyone help? I am simply trying to connect the data set to power bi using one of the OData feeds. Bu it says "Failed to save modifications to the server. Error returned: 'OLE DB or ODBC error: [DataSource.Error] OData: Request failed: The remote server returned an error: (500) Internal Server Error. (This OData feed does not exist). '."
